Have posted on this page after a very long time ...big gap :-)...anyway, the main page has always kept the latest Mumbai weather updated...

Mumbai is having,  almost normal , and nights slightly cooler, 
(and quite happy about it) weather since the last the graph shows.

Expected to continue in the same range, 32/33c-20c for the next 3 days. Expecting temperatures to rise from Saturday by a few degrees, as well as increase in humidity levels.

Same reasoning with Pune, expect that the day is a degree above normal, but compensated by the night, which is a degree below normal.

Monitoring Mumbai's Mangroves:

  Mar 19th 1988

 Jan 30th 2017

Many of the rivers, creeks, and other waterways that run through Mumbai are flanked by green. These areas are havens for mangroves — short, shrubby trees with waxy leaves and tangles of finger-like roots that rise out of the swampy, sandy areas.
In this booming city, India’s largest, mangrove forests have historically been overlooked. Large tracts of them were removed as part of land reclamation projects, and many of the mangroves that remain have become dumping grounds for garbage and targets for developers and squatters.
These days, Indian authorities are trying to change that. As the key role that mangroves play in flood control, water quality, and wildlife habitat has become more widely appreciated, Mumbai has been the focus of new efforts to clean up mangrove areasfence them off, and more aggressively monitor and protect them.
The monitoring efforts will soon get a boost from satellites. In November 2017, the Maharashtra Forest Department signed an agreement with the Indian Space Research Organization (ISRO) to begin using satellite imagery to monitor mangroves in the state, including Mumbai. Images will be sent to the forest department on a monthly basis and will make it easier for managers to identify where mangrove loss and gain is occurring.
The Landsat images above offer an example of how satellite imagery can be used to track changes to mangroves. These images are centered on Thane Creek — a key waterway that runs through the city. It is home to more than 59 square kilometers (23 square miles) of mangroves, according to one recent assessment from the Forest Survey of India.
The first image was acquired in 1988; the second was captured in 2017. The dark green areas along Thane Creek are mangrove forests. The buildings and roads of urbanized areas appear grey and white. Both images were captured around high tide. Turn on the image comparison tool to see where the city has expanded and where mangrove cover has changed.
Between 1988 and 2017, urban development encroached on mangroves in several areas. For instance, the Deonar landfillspread significantly, and new residential and commercial development emerged along the northern stretches of Thane Creek.
At the same time, the images illustrate another ongoing trend that bodes well for Mumbai’s mangroves. Over time, the deposition of sediment has narrowed the channel and allowed some mangroves to spread closer to the center of the creek. It is this type of expansion that has caused some researchers to report an increase in mangrove cover in Mumbai over the past 15 years, even as other scientists have reported significant long-term declines.
“On the whole, we have seen stark declines in mangroves in Mumbai in recent decades,” said Eric Vaz of Ryerson University. “But it is certainly true that you can find some areas where there has been some gain, too.”

Image of recent smog over Mumbai..

Posted 27th December 2015

Dated 27 Dec 2015.. (max temp of 26th Dec afternoon / min temp of 27th Dec morning)


The micro climates of Mumbai region and Goa state are more pronounced in winter season (Dec to Feb).As they spread from the Arabian sea towards the base of the Western ghats, the geography of the region creates such micro climates.
Generally, Mumbai gets cooler in aftermaths of western disturbances .Goa is affected to a lesser extent as it lies further south.
The far eastern suburbs of Mumbai (Badlapur) get affected by cold waves of the Deccan plateau region as well.



1)      Santacruz (Airport) : Today’s temp: max 33 c / min 14 c

This station is located 4 kms inland from the Arabian Sea in western Mumbai near Juhu beach.
This station currently represents Mumbai in all weather reports. This station shows considerable fluctuations in temperatures during winter depending upon prevailing wind directions. (eg. During past one week ; it has seen minimum temp ranging from 11c to 18 c , maximum temp ranging from 28 c to 33 c ).

a) It shows affinity to western disturbances.
b)  This location does not show much affinity to cold waves of the Deccan plateau region.
Eg. When Pune (Deccan plateau) recorded minimum temperature of 6.6 c yesterday, Santacruz was cozying @ 16.6 c  (* Tip – compare with Badlapur)

For a coastal location, can become very dry at times. Eg. for the past couple of days humidity during day as well as night time is below  40% and scooping down to 20 %.

2)      Thane city (20 kms NE of Santacruz station )  : Today’s temp: max 32 c / min 14 c

This central suburb is located near to the Thane creek, almost 20 kms inland from Arabian sea. This station shows temperatures almost similar to Santacruz station. Consistent readings are required from this location for further clarity.

NATIONAL PARK is located in WEST/CENTRAL region (almost 50 sq.kms. area in Mumbai). The temperature inside and around the park are definitely cooler than the surroundings.



3)      Colaba (25 kms south of Santacruz station ) : Today’s temp: max 31 c / min 20 c

This station is located at the exterme south tip of Mumbai region, where the sand meets the sea.
This station represented Mumbai weather before 1960.This station records higher min temp as it’s by the sea, but this also helps it to record mildest afternoons temperatures in the Mumbai region. Lowest min temp this season @17.2 c .

      Vagaries Club  (15 kms south of Santacruz station ) : Today’s temp: max 32 c / min 16 c

This South Mumbai station is located very near (1 km) to the Arabian sea. It is in the midst of an open green area.This station shows higher min temp and lower max temp than Santacruz station  Rajesh sir  maintains it .Lowest min temp this season @15.5 c



      Badlapur (40 kms east of Santacruz station ) : Today’s temp: max 28 c / min 10 c

This far eastern suburb of Mumbai is located more than 30 kms inland from the sea. This location helps it to record lower night temperatures in Mumbai region, consistently .Thanks to Vagarian Abhijit for maintaining it.

This location shows dual ability :  
a) Gets affected by western disturbances.
b) Gets affected by cold waves of the Deccan plateau region as well, as it is showing for the past few days.
Eg. When Pune (Deccan plateau) recorded minimum temperature of 6.6 c yesterday, Badlapur dropped to single digit @ 9.4 c (* Tip – compare with Santacruz)



    Palghar (70 kms north of Santacruz station ) : Today’s temp: max 31 c / min 13 c

This  far northern suburb of Mumbai is located 10 kms inland from the Arabian sea.
All in all, relatively cooler version of Santacruz station.

Like Santacruz,
This station shows considerable fluctuations in temperatures during winter depending upon prevailing wind directions. (eg. During past one week ; it has seen minimum temp ranging from 9.6 c to 15 c).

a) It shows affinity to western disturbances and because of it’s more northerly location (20 N) can record single digit minimum temp.
b) This location doesn’t show much affinity to cold waves of the Deccan plateau region.
Eg. When Nashik (Deccan plateau) recorded minimum temperature of 5 c on 25th Dec , Palghar was cozying @ 14.6 c (* Tip – compare with Badlapur)



Located at a southerly latitude ( 15 S) , Goa lacks the penetrative winds .Hence, it’s afternoons always remain warm but nights can get cooler on occasions (but single digit minimum temp have never been recorded at Goa)
Can be feebly affected by a western disturbance.



)      Panji  : Today’s temp: max 33 c / min 20 c

This station is located close to the sea  .
This station currently represents Goa in all weather reports. This station records higher min tempsrature as it’s by the sea . Lowest min temp this season @20.2 c .For a coastal station , can be dry at times and consistently records higher afternoon temperatures  (32 to 34c).

2    Mormugao (Port /Airport , 10 kms south of Panji) : Today’s temp: max 34c / min 23 c

Inspite of greater proximity to the sea, this station records higher temperatures than Panji. Generally remains warm.

     Kankon ( 60 kms south of Panji) : Today’s temp: max 34 c / min 17 c

This station is located 2 kms inland from the Arabian Sea, in the heart of rural South Goa near Karnataka border. Inspite of being near the coast, records lower night temperatures than urban Panji  because of it’s rural settings (specially after sunset , temperature drop can be felt).
It can be dry at times .



      Mhapsa city  (15 kms north of Panji): Today’s temp: max 33 c / min 17 c

This station is located 10 kms inland from the Arabian Sea in North Goa. It’s the gateway to Calangute beach.
The inland location helps to record lower night temperatures than coastal Panji. It can be dry at times and consistently records higher afternoon temperatures  (32 to 34c).

      Pedne  (30 kms north of Panji): Today’s temp: max 32 c / min 15 c

This station is located 15 kms inland from the Arabian Sea in North Goa near Maharashtra border. In Goa, some semblance of a winter can be felt here (specially after sunset , temperature drop can be felt).
The inland location helps to record considerable lower night temperatures than coastal Panji. It can be dry at times .It records the maximum temp of the day around 1.30 pm and then generally cools off.
All in all, relatively cooler version of Mhapsa city.Temperatures of Pedne almost match with that of Vengurla  (South Konkan , Maharashtra).

Monthly  & Monsoon Performance depicted by Vagarians Displayed Below:

 From Vagarian Puneet:

From Vagarian Tejas:



After a good spell of Bountiful rains from BB-6, Maharashtra is now in for an almost dry spell next 5 days. This is now beneficial for the farms and standing crops. We understand, tht the recent rains in Marathwada has resulted in almost all the small dams overflowing or to the brim. This has brought the ground water table higher, and the local wells have seen a ris eof 12-15 feet in their water levels. More rise expected in wells as the water percolates into the side bores. Even the standing crop has got enough soil moisture till harvest time. This late rainfall was more helpfull as it was accompanied by lightning. Remember, that when lightning flashes across the atmosphere, it momentarily "consumes" up most of the oxygen from the air, resulting in a temporary increase in Nitrogen in the air space. This Nitrogen dissolves in the falling rain, and as we all know, Nitrogen is a very useful fertiliser for crops.

Retreating thunder showers are likely in interior Maharashtra after next Monday 28th September.

Article on Marathwada to be Printed in Lokmat Times of Monday 3rd August:

Weather Watch
A miserable month for Marathwada
It has been a miserable month for Marathwada, and  is suffering from extreme far as the Monsoon rains are concerned. The deficit in the Marathwada region is -56%.
In statistical terms, out of the normal 336 mms normal rain required on an average for Marathwada, only 146 mms have been received.
..Aurangabad has seen only 14 mms this July. But this is not far, or negligible from the record low which was 11 mms in 1971.
Parbhani measured only 21 mms this year, of course this being the driest July on record (Previous low was 15 mms in 1971). Nanded has received 165 mms as on date, against a normal of around 410 mms.
Osmanabad saw just 18 mms in July, and the total from June being just 87 mms, while normally the total should be 325 mms.

This has resulted in a very poor water storage position. The major dam, Jayakwadi is only 6% full, Purna Yeldari ( Parbhani) is only 1 % full, Purna Siddheshwar (Parbhani), Manjra (Beed) and Majalgaon (Beed) are at 0%, Lower Terana (Osmanabad) is also 0%, Sina Kolegaon (Osmanabad) is also at 0%. Manar and Vishnupuri in Nanaded are at 4% and 14% respectively. Upper Penganga ( Nanded) is at 15%. The best of all reservoir seems to be Lower Dudhna (Nanded) which is still at 25% only.
So, on an average, all major and medium Dams and reservoirs are full only 7% in Marathwada.
Nagpur regions Dams and reservoirs are 36% full. All Maharashtra average for Dams and reservoirs are 38% full in Storage.
The standing crops in Aurangabad region now are in a precarious condition. The Jowhar, Maize, Moong and other crops have a standing capacity to survive for only 4/5 days without water, that is immediate rains. The small time earthen dams and rivulets are dry, and the wells are getting deeper in water levels.
The cotton crop may withstand another week, probably. Aurangabad region may see light showers next week, but in pockets, not widespread. Region may get around 5-10 mms. 
The next week sees light to medium rains in Vidharbh. Akola District may see some meaningful increase in rains on Tuesday/Wednesday for a couple of days. The district may get around 15-20 mms per day Tuesday/Wednesday and Thursday. 

For Mumbai SantaCruz, July 2015  was the 3rd driest July on record..This July (2015) saw 360 mms of rain, and the previous lowest was in the drought year 1971, when 385 mms was recorded, and all time lowest was in 2002 when only 103 mms was recorded in July..

Mumbai Weather Summary...2014 (From Rohit Aroskar)

Took these Pics while flying over Matheran on Monday 15th December ....
Matheran is a Hill Station in the Indian state of Maharashtra. It is also the smallest hill station in India. It is located on the Western Ghats range at an elevation of around 800 m (2,625 feet) above sea level. It is located around 90 km from Mumbai, and 120 km from Pune. Matheran's proximity makes it a popular weekend getaway for urban residents. Matheran, which means "forest on the forehead" (of the mountains) is an eco-sensitive region, declared by the Ministry of Environment and Forest, Government of India. It is Asia's only auto mobile -free hill station

Maharashtra Report on Monsoon

Marathwada , at the end of September, was at -42%, having received only 399 mms against a normal of 683 mms.
Total live storage of all dams in Marathwada is ok at around 75%.
However, some sporadic thunder showers in the first week of October have added soil moisture and will help the rabi crop.
Jayakwadi, the main and huge source of water storage was better placed than in 2013 and 2012.
This year, the storage level is 45% of the full, better than 33% last year and much much better than only 3% in 2012 !
The level of Jayakwadi is critical and important, but is controlled by discharges from dams in Nashik, and sometimes outflows are allowed from Jayakwadi for downstream.
Crop wise, almost 40-45% of the Kharif crop has withered due to poor rains in Monsoon (Marathwda).


Thunderstorm Pics from South Mumbai...approximately 35-40 trees were uprooted in the 90 mins Storm....Pics by Salil, Mangesh and Abhijit

Thunder Showers may start in a few days around Mumbai....Posted 16th Evening-

Posted September 6th 

Mumbai: The 2 IMD stations of Mumbai have touched their normal rainfall figures in spite of severe "ups and downs'' in a roller coaster ride. 
The Monsoon set in on June 16th  over the city.
June was dry!. The driest EVER in Colaba , when this South Mumbai station received a meagre 5 mms of rain in the Month. Sanata Cruz was no better with only 87 mms in June. A very dry June !
After hitting the bottom, the roller coaster took an upward journey. A very wet July, with tremendous rains, and resulting in the wettest July EVER for Santa Cruz , with 1469 mms in the month....Now thats something.
But, it not over. August was going dry again. Save the recovery in the last 2 days of August, rains were minimal. But, the good rains in frst week of september pushed up the seasonal total to 2050  mms at Colaba and 2245  mms at SantaCruz. The normal seasonal toatl till  end September required is 2053 mms for Colaba and 2232 mms for Cruz.

Lakes supplying water to Mumbai are also showing good levels.Most of them are nearly on the overflow mark, and I would expect all to overflow next week. 
Water supply to the city could last for a year at current position and levels.

Mumbai will be partly cloudy with sunny spells on sunday> A few passing showers.
Monday will be partly cloudy with some showers in the evening. A few heavy showers in parts of city. Around 10-15 mms during the day.
Tuesday rains increase, with intermittent rain in the day. A few thunder showers will be very heavy post noon, leading to local flooding. Around 75 mms in the day.

Mumbai Colaba received 23 mms and Scruz 15 mms in 12 hrs from 08.30 am Monday 1st Sept


Come Saturday Evening, and the forecasted Thunder storms came..
Heavy Storms reported by Junaid, Abhijit and Puneet from Eastern Outer Townships of Panvel, Badlapur and Dombivali.

Steady drizzle with Thunder here in South Mumbai since 6.00 pm IST

Thursday Morning,21st August, Mumbai got a surprise thunder shower around early morning....A Vortex in the upper atmosphere near Mumbai caused a short but severe thunder shower in Mumbai. Lasting 2 hours overall on Thursday morning, the peak rainfall from 7 am to 8 am brought the major rainfall. Vagaries 38 mms, Colaba 33.6 mms and Scruz 29.6 mms. 
Dadar recorded 96 mms, Worli 81 mms, Dharavi 55 mms.
Min remained high at 27c...and yesterday was odd with max at 27.8c, and min Wed morning was 27c.

Mumbai was very cloudy, but as expected, just 1 mms of rain at Scruz.
Pune , being in the Thunder activity zone, saw 23 mms till 5.30 pm Tuesday. 

Delhi day soared to 37c Tuesday.

Posted Monday 18th Afternoon:
Next 2/3 Days:

1. A ridge gradually forming in the central Arabian Sea.

2. Direction of winds along West Coast of India will change to NW.
2(a). Mumbai gets very little rainfall of < 5mms per day from Monday through Thursday. Though sky can be cloudy, actual precipitation may be light showers in some parts.

3. In Madhya Mah, interaction of North winds with West winds could bring thunder showers popping up from Nasik Southwards till Kolhapur on Tuesday through Thursday (Pune falls in the zone).
Mumbai Eastern Outer Townships may get the stray Thunder Cell in the vicinty

4. Clockwise winds at 700 mb levels indicate the formation of an upper ridge in NW India from Monday. Through the week, the anti cyclone may bring almost clear skies in NW India and Delhi regions. We may see the days touching 40c in NCR or Haryana. Seeing some improvement from Saturday 23rd.

For Many Palces in Maharashtra, The Driest June Ever...Compiled by Abhijit

It's official that Maharashtra regions, specially coastal Konkan,  many towns/cities have broken all time record of lowest rainfall for June !

 It is one of weakest onset of SWM over Konkan region ever..Because we see many cities previous all time low rainfall records 

Colaba saw 91.7 mms in 1947
Alibaug saw 147 mms in 1947
Ratnagiri saw 236 mms in 1952
Harnai saw 228 mms in 1966

And this current June 2014, saw new all time lowest rainfall record for all above cities this year and much less rain too than previous record !

Colaba 55.2 mms
Alibaug 95 mms
Ratnagiri 178.6 mms
Harnai 182.7 mms 

Hoping that such Driest June never comes in future and current new all time lowest rainfall record should never get broken !!

Posted Monday Evening: As forecasted, the maximum Temperature jumped to 35.8c at Scruz on Monday.....

Mumbai City may get the Pre Monsoon showers ( Thunder) from 1st/2nd June onwards

Posted Sunday ( 18th May) Evening:

Mumbai: Next 4 days....19th May - 22nd May.

Partly Cloudy days. Seeing some towering Thunder heads in the East on Monday 19th. Some drifting of alto cumulus in the evening from the East. Nights will be partly cloudy and stuffy, humid and sweaty. North/North-West winds will be sharp in the evening at around 25-30 kmph.

Hotter next 2 days in the week ! As the humidity increases, with passing day,warmer real feel temperatures will make the day sweaty.
Temperatures will be between 36c and 28c on Monday and Tuesday. But, humidity more and temperature less on Wednesday and 34c and 28/ harsher real feel !

On Sunday evening, Eastern Outer townships got a dust storm with thunder. Matheran received rains (about 8 mms as per unofficial report). Intense rains seen around Matheran and rain patch in the North...

Eastern Outer Townships:

Possibly will see some Cumulus developments on Monday 19th, and with cloudy skies, night temperatures will show a rise as they get stuffy. 
Tuesday, the outer towns will be hot, and with the temperature at 37/38c and humidity at 65%, its going to be un comfortable. Nights warming up to 27/28c.
Temperatures shift down 2 degrees from Wednesday.

Pune: Partly cloudy. Tuesday 20th some Cumulus developments in some parts. Otherwise, days will be around 40c, and nights rising to almost 25/26c.


Posted Saturday Morning:
Mumbai, Saturday 26th, Sunday 27th and Monday 28th will not be as comfortable as the temperature readings will show. 

The day's Max on these 3 days will not go over 34c. Ok, good !. But the high humidity that will sweat the city will be around 70-80%. This will make a Real Feel temperature of around 39/40c in Mumbai.
W/NW winds will bring in cooler sea breeze, and a good lot of humidity with it. In fact, we have WNW winds upto the 850 level over Mumbai, and a ridge at the 700 level. This will surely block the humidity and warmth on the ground level.
So, as a result, the nights will be around 27c...warm and stuffy !

Clear skies.

Posted Thursday 15th Night:

Mumbai finally showing signs of reducing temperatures...Maximum on Thursday was 36 5c at Scruz ( reduced by 2.5c from Tuesday) and it was 33.4c at Colaba, educed by 3c. 

As mentioned earlier, we can expect the mercury to reach 35c by Friday. Expect NW winds to bring in sea breeze and bring the temperatures down...and the humidity up !

The minimums are also as per our estimate, 26.4c at Colaba and 25.0c at Scruz. 

Posted 24th April:

And Mumbai Het continues for the 4th day running....
Query from Abhijit: " Sir : Why so much of heating in just 30 -40kms inland to ARB sea this year ? Int Maha areas like Nashik, Pune Aurangabad yet to see their first 40c temp ! And we in interior coastal Konkan had 40c+ for 5 times ! 4 of them in Apr itself..?"

Well, this wind chart explains it all...

The wind Chart..shows NE winds in the Northern Coastal (West)
means bringing very dry NE winds and pushing away the sea breeze and humidity...there is a ridge along coast at upper level that is preventing hot air from rising, and cool sea breeze not able to enter coast, so even the konkan interior heats up..ridge always stubborn and hot in this month...

That is why even the nights are warm, Vagaries recorded a min of 28.4c on Wednesday morning and 28.0c on Thursday.
 Surat was 41c and many North Konkan Cities like Thane, Kalyan and Badlapur were over 40c.

Posted 22nd April 2014:

Northern Suburbs of Mumbai received light showers on Monday , 21st April night. Parts of Ghatkopar, Goregaon, Sion and Vikhroli got medium showers with tunder. Thane, ad surroundings too received good showers in the night.

meanwhile, Santacruz soared to 39c on Monday, highest after 2009 in April when it had touched 40.6c on th 2nd of the Month. The highest ever for April is 42.2c, on 14th April 1952. The lowest minimum at Sanata Cruz ever for April was in 1968 when it dropped to 16.9c.

Colaba was 36c. The highest in April ever for Colaba is 40.6c, which was on 19th in 1955. The lowest minimum for Colaba ever was 20c in 1905.

Vagaries recorded 38.1c on Monday.

Mumbai is the usual. Days are in the predicted 33/34c range. But, things could be a little more warmer on Divali day. East winds are going to keep the days warm at 34c, but maybe at 35/36c on Sunday. Nights will show some variation by dropping to 22/23c.
Mumbai may see some light clouding on Monday, raising the night temperature.

Pune remains partly cloudy for Divali, with days around 31c and nights at 17/18c.

Table prepared by Jayesh Mehta for vagaries

Saturday 13th July 2013:

On Friday, Mumbai was flooded, traffic snarled and trains were late...was it heavy rains,or mismanagement ?  

The rain amounts put up below, for Friday's rain are heavy, no doubt, but hasn't Mumbai seen much more than this before ? Even double this amount is normally expected in Mumbai in June and July...anyway..

Rainfall from Friday morning to Saturday morning:

Dadar and Wadala 115 mms, Chembur 111 mms, Borivali 107 mms, Worli 104 mms, Dahisar 90 mmms, D Ward (Nana Chowk)  65 mms, Vikholi 59 mms.
IMD Colaba 49 mms, Sanat Cruz 108 mms and Vagaries 87 mms.

The average for Western Suburbs was  83 mms, Eastern Suburbs was 86 mms and Island City was 85 mms.

(The average rain amount put up by vagaries for the period was upto 55 mms (For Mumbai City, so overshooting by 30 mms).

The outer townshps rainfall will be put up by noon (by Abhijit). But from figures received for Northern Townships, Vasai recieved 133 mms till 8 pm Friday.

Lake levels and rain amounts will be put up on this page as soon as they are confirmed..anyway, why are we so excited about Tulshi overflowing. Water supply to Mumbai is 3500 mltrs/day, and only 40 mltrs is taken from Tulshi. Its like adding a bottle of mineral water in your overhead water some say "the mineral water bottle has overflowed."

Wednesday 5th June.: Partly cloudy day, getting overcast by afternoon. Thundery developments by eveining, with showers in some parts.


Mumbai Outlook till Sunday, 26th May:;Posted on 21st May Night.

Going on schedule from last Mumbai report of 19th, the developments seem to be on stream.
Vagaries had calculated the formation of an off shore trough along the West coast end of May.
The formation of a trough seems possible, with the NW winds (High pressure effect) relenting to some extent due to organised cross SW winds in the Arabian Sea and Somali current showing the effective SST. And with the seasonal low possibly deepening to 994 mb this weekend, creating a good gradient, what happens is given below:v

Wednesday 22nd /Thursday 23rd :  34c – 28c: Periods of clouds, with high clouds of last 2 days relenting back to low clouds. Morning will be more dense.  Winds will be SW and real feel will be 37c in the day.

Friday 24th:  35c – 29c: Partly cloudy, low cumulus clouds gathering by evening..Days will be windy with SW winds and real feel factor will be 37/38c.

Saturday 25th: Getting overcast by evening. Thunder clouds will be seen developing by noon, and towering over the eastern sky.
Meaning overcast with thunder heads for the outer townships, possibly showers in some parts or vicinity.

Sunday 26th: Cloudy morning getting overcast. Thunder heads with towering cumulus forming in the east.  By evening, the eastern horizon can get overcast as the thunder showers drift towards city. Some parts can get showers with lightning.
Outer townships will get thunder showers on Sunday afternoon/evening.


May Weather of Mumbai Weather and Outlook for the Month:..Posted on 19th May 2013
(This is going to be a pleasant reading for our up country and North India, Mumbaites, do not grumble).

SCZ 33.4 - 24.9c  and Clb  34.1 - 27.1...The average Temperature for Mumbai this May as on date.
This is the current temperature range experienced in Mumbai. And I would say its around normal for this time.
A humidity ranging between 60% and 80%, has been the trend in the city for the last 10 days now.

For  Mumbai..May 2013 is slightly below normal. With light and under developed cumulus clouds and a W/NW wind keeping the evenings just about manageable.
In fact, the weather last 30 days Mid April through Mid May has been just
below normal, in fact a bit below normal during May.
Diagram put shows a below normal by 042c.

There has been no rainfall yet from October 24th, 2011 thru May 20th 2012
in Mumbai.
That means straight 209 days (till 21st May 2012) without a drop of rain recorded !!

Last Year, up to June 5th 2012 , Mumbai had 223 straight days without recording any rain !

I have no record for the number of straight days without rain for Mumbai. If readers have any information on this, please put it up on Vagaries..would be very interesting.
In previous years the city has had many April/Mays without a single mm of rain. And it has no bearing on the SWM rains later.

The wettest May, as far as my records show, has been in 1918, when the city (Colaba) was drenched with 279 mms. By coincidence, 1918 was a drought year in India, with one of the lowest average rainfall on all India basis, 65 cms, against a normal of 89cms. That is -27%. Absolutely a severe drought year.

The wettest May at S'Cruz was in the year 2000, with 388 mms of rain.
Mumbai's (Colaba) last 5 years' May rainfall has been: 2012=2012 0 mm, 2011=1 mm, 2010=0 mm, 2009=2 mms, 2008= 0 mms, 2007=1 mm, 2006=135 mms.

Outlook for May:

May 20th -25th: Partly cloudy skies, specially in the mornings. Temperatures going in the 33c - 27c range. Humidity in the 65%-80% band.

May 26th -29th: Expecting some increasing cloudiness after the 25th, indicating a rise in the night temperatures. Morning clouds will be thicker, Cumulus clouds will be seen towering late afternoon. Temperature range will be 34/35c-28c. Humidity will be in the 70%-85% band.

May 29thst-1st June: Thunder Heads will start to show up in the East. Some tending to drift and precipitate over parts of Mumbai City.

For Mumbai, I would like to maintain estimate of monsoon arrival dates, June 8th/9th.

Much awaited regular Pre- Monsoon evening thundershowers could cool the city from around 30th May.
Regular Monsoon set could be around the 8th/9th of June. Expecting initial commencement to be sluggish.

However, pre-monsoon thundershowers would also commence in the outer townships, Lonavala/Pune/Khandala/Matheran hills by the 28th of this month.
Expecting Mahableshwar to get its first pre monsoon showers by the 27th of May.

Quantum forecast for the Mumbai City for June will be 675-725 mms.

If need be, situation could go in for some revision changes, depending on the developments.

Mumbai Lakes Water Storage as on 13th May 2013: 564 Mcum (Approx=32% of capacity) and approx =4.2 months storage).

This is the synoptic situation as on today.


Konkan Summer Analysis from Rohit...

Konkan and Goa subdivision till now : 

This sunny subdivision has received the least rainfall amongst all the met subdivisions of India from 1st Jan -15th May 2013.The northern 2/3rd of this subdivision has hardly received any rainfall (0mms at most stations)from the start of the year (this is almost normal)..

This is the subdivision which gets 95+% of its annual rainfall from SW monsoon(291.4 cms) and ranks 2nd amongst the met sub-divisions which receive highest SW monsoon rain .. 

Monday/Tuesday: Sunny and hot, with High humidity making it sweaty and uncomfortable. Temperature range (Scruz) 35c - 25c. Real feel will be 40c. Colaba minimum will be 27c.

May Day, Wednesday: Sticky and sunny. Winds veering westwards increases the humidity and real feel will be 42c on a day's high of 36c. Low at Scruz will rise to 26c..

Outer townships:
Monday/Tuesday: Sunny and hot. Blazing sunshine will shoot the mercury to 39c, and nights too will be warm at 23/24c.
May Day, Wednesday: Strong W/SW winds will bring in humidity, and make it very hot at 39/40c. Warm temperatures till late evening.

:Very Hot and Sunny. Day temperatures rising to 41c and nights at 23/24c.
May Day Wednesday: Hot and still rising to 41/42c. Precautions against heatstroke necessary.



Nagpur: Very Hot ! Expected to touch 45c/46c next 2 days. May Day will be extremely hot at around 45c-46c. Nights will be uncomfortably high at 28/29c...


Sunset from S.Mumbai on Wednesday 13th March..

Mumbai Supply Water Lakes levels are at 5.60 lmltrs (5.36 lmltrs). Supply can last for another 150 days taking the minimum drawable level into consideration.

Posted on 3rd March 2013..@ 6 pm...

Konkan (including Mumbai) and South Coastal Gujarat heats up and temperatures are nearly touching 40c in March first week.

Is that something unusual ? I have started hearing and "feeling" the GW bug around me. Yes. "Its never been soooo hot in Mumbai this early" to "its surely GW and If Mumbai is 38/39c now, what will happen in April and lets just not discuss May"...and so on....
But whats so unusual about this ? Nothing ! In the last 10 years, Mumbai has crossed 38c earlier 7 times (out of 10). The highest ever at Colaba of 41.6c was in March 2011 and highest ever in Santa Cruz of 42.2c was in April 1952.

The first 40c anywhere in India for the year 1981 was in  Mumbai on 3rd March and again Mumbai was the first to touch 40c in 2007, again on 16th March. See Vagaries Extreme Blog)
Other places along the west coast too have similar highs in March. Ratnagiri, highest ever for March was in 2011 at 39.6c. Previously also in 1922, it had touched 38.9c in March. Panaji touched 39c in March (12th) 1979.Dahanu too, is famous for its 40.5c touched on 30th March 1982.
And Surat and Bharuch have got a 44c record for March(1973 and 1959).

So, if at all i have to accept the GW theory, then i might say the GW bug has been amonst us since the last 60 years....and consequently nothing new and untoward for us to worry about now....

A change from the winter routine pattern causes this untoward and high rise heating specially along the west coast.
The absence of a WD, and the emrgence of NW winds in the extreme North of the Sub continent plains, causes and gives rise to a High pressure area at Sea level and upto 850 mb, somewhere in central Rajasthan, stretchig SE into North MP. A prominent ridge also gets established along the west coast from Goa till the high pressure. See here 
Thus, we see  gush of NW winds at sea level North of Delhi, and turning clock wise to take a clean Easterly direction thru Maharashtra and flowing out into the sea thru the Maharashtra and South Gujarat coast. 

This inland Easterly flow prevents the cooler sea breeze from setting in and controlling the day temperature. We notice, that till exactly around 1.45 pm, the East winds are having a "field day" , and create a dry atmosphere and prevent the cooling sea breeze from taking any effect. 
Thus, the temperatures rise exorbitantly to 38/39 levels till then.

After 1.45 pm, the W/NW winds take over (mercifully) and continue till night, that brings in the wide variation in the day and night temperatures.

Now, this is specially effective in SCruz and not Colaba station as the Easterlies do not really "hit" Colaba directly. Colaba is surrounded by the sea on the East and West, hence the effct of these tormenting winds are minimum at colaba.

Another factor allowing these Easterly winds to play mischief is the "yet-to-form" vertical line of wind dis-continuity along the Peninsula. This normally forms in April, and is one of the parameters in the SWM advance (see MW series). This would not allow the easterlies to dominate and would divert them in similar situations to a NE direction in the Eastern Peninsula (causing heat there).

But, a repeat of a similar occurance in March would restrain me from announcing a timely arrival of the SWM..

Mumbai Deluge 26th July 2005:

Meteorologically, how did it Happen ?

Though the heavy rain had been falling during the previous week, the 26th Of July 2005, Mumbai recieved the heaviest of rainfall, ever for any place in India in a 24 hr time frame.
July 27th 2005, morning readings at 8.30 am, saw Mumbai Santa Cruz recording 944.2 mms of rain in the previous 24 hrs. 
Though all records show it as the highest for any place in a day fro India, it is not so. Vihar Lake, recorded 1040 mms in the same period on the same day.
The rains that struck Mumbai on 26th July 2005, were the worst the city had ever known..and the flooding was un precedented. 
Although the rainfall was much faster and greater in quantity than ever before, it should not have caused the hardships and deaths it did. Why did it not simply drain away? 

Mumbai has hereafter grown rapidly, buildings have replaced parks and open grounds that used to soak up rain water.

Mumbai's antiquated and poorly maintained drainage and the blocked and choked Mithi River prevented rain water from flowing away.The Mithi is a seasonal river, that swells during heavy rains.The worst hit areas was Kalina,which is next to the Mithi River.Low lying marsh and mangroves used to absorb any excess water if the river oversplilled its banks. But lately, construction has encraoched on its banks, and the debris dumped in the river.

On the day of the deluge, as rain water ran down the naroowed river, and met with the high tide waters, the banks overflowed.
Another rising problem are the diminishing mangroves along the coast. These are being removed, and reclaimed from the sea. It is increasingly depriving Mumbai from the natural barrier from the seas.
Bittu Sahgal ;" its a case study of the collapse of urbania in India."

Posted on 20th May: 

Mumbai Weather Outlook:

33c - 27c. 
This is the current temperature range experianced in Mumbai. And I would say its around normal for this time.
A humidity ranging between 60% and 80%, has been the trend in the city for the last 10 days now.

May 2012 is normal. With light and under developed cumulus clouds and a NW wind keeping the evenings just about manageable.

In fact, the weather last 30 days Mid April through Mid May has been just about normal, in fact a bit below normal during May. 
Diagram put shows a miniscule rise of 0.09c. 

There has been no rainfall yet from October 25th, 2011 thru May 20th 2012

in Mumbai. 
That means straight 208 days (till 21st May 2012) without a drop of rain recorded !!

I have no record for the number of straight days without rain for Mumbai. If readers have any information on this, please put it up on Vagaries..would be very interesting.

In previous years the city has had many April/Mays without a single mm of rain. And it has no bearing on the SWM rains later.

The wettest May, as far as my records show, has been in 1918, when the city (Colaba) was drenched with 279 mms. By coincidence, 1918 was a drought year in India, with one of the lowest avaerage rainfall on all India basis, 65 cms, against a normal of 89cms. That is -27%. Absolutely a severe drought year.

The wettest May at S'Cruz was in the year 2000, with 388 mms of rain.

Mumbai's (Colaba) last 5 years' May rainfall has been: 2011=1 mm, 2010=0 mm, 2009=2 mms, 2008= 0 mms, 2007=1 mm, 2006=135 mms.

Outlook for May:

May 20th -25th: Partly cloudy skies, specially in the mornings. Temperatures going in the 33c - 27c range. Humidity in the 65%-80% band.

May 26th -30th: Expecting some increasing cloudiness after the 25th, indicating a rise in the night temperatures. Morning clouds will be thicker, Cumulus clouds will be seen towering late afternoon. Temperature range will be 34/35c-28c. Humidity will be in the 70%-85% band. 

May 31st-1st June: Thunder Heads will start to show up in the East. 
The highest ever night temperature for Mumbai I have on record is 30c. There is no official record available to confirm the highest minimum in Mumbai.

For Mumbai, I would like to maintain my previous estimate of monsoon arrival dates. 

Much awaited regular Pre- Monsoon evening thundershowers could cool the city from around 3rd/4th June. 

Regular Monsoon set could be around the 11th/13th of June. Expecting initial commencement to be sluggish.

However, pre-monsoon thundershowers would commence in the Lonavala/Pune/Khandala/Matheran hills by the 29th of this month. Expecting Mahableshwar to get its first pre monsoon showers by the 27th of May.

Quantum forecast for the city for June has been put up earlier.

If need be, situation could go in for some revisional changes, depending on the developments. This is the synoptic situation as on today.

The Latest water storage of Lakes supplying water to Mumbai. 

This latest position obtained as on 7th May 2012:

Full capacity is 1583 Mcum.

All the lakes combined have a current storage of 656 Mcum as on 7th May 2012. Overall combined existing storage is 41% of the full capacity. 

The maximum stored is in Bhatsa at 45%, and lowest storage is of Tansa at 17%.

Same date last year (2011) the lakes had a combined storage of 699 Mcum.@ 44%

2010 the storage was 474 Mcum and in recent years, the lowest as on 1st May was in 2008 at 446 Mcum.@ 28%

Mumbai Forecast: 

Thursday,10th:  33c-26c. Increasing humidity by the weekend will see the highest humidity this month as yet. Mild unstable atmospheric conditions will see some cumulus clouds towering to medium heights by afternoon. 

Friday,11th/Saturday,12th/Sunday,13th: However, the day temps will fall by a degree to 32c later this week on Friday. The sticky weather conditions will make it unbearable, with the "real feel" being 40c,  making the degree fall in the day insignificant. Nights will remain around 27c.  

Pune: Shiraz reports of a light thundershower in Mahableshwar today (Wednesday) and feedback of light drizzles in Pune (Race course and Mainstreet areas) on Tuesday night. In line with Vagaries forecast put up last Sunday.

Thursday/Friday: 38c-22c. 50%* chances of rain on Friday.

Saturday/Sunday: 39c-22c Will see partly cloudy skies in the afternoon. some cumulus towers will be seen developing by evening.

Image of Mumbai Coast at 5.30 am (IST) Thursday.

Warm and stuffy last night, Wednesday night, with the minimum not going below 28c on Thursday morning. Partly cloudy with cloud ceiling of 3000-10000 feet. Winds changed to Sw after 1 am Thursday. Expect clouds to thicken in the evening today.
A UAC has formed over Haryana, and a trough runs from the system doawn south thru Saurashtra into the North Arabian Sea. hence clouds cover the Saurashtra peninsula too. A trough runs from east Madhya Pradesh to Kerala persists across Vidarbha, Telangana and south interior Karnataka. 

Overnight Thunderstorms have lashed the Lakshadweep Islands, with Minicoy receiving thunderstorms almost thru the night.

Posted on 2nd April 2012

Ron, it seems from this close up image of the West coast, taken at 11.30 pm IST Monday, that the trough line has moved towards the coast. This is temporary, and will move east again.

Notice the Thunder Heads in Karnataka and S.Mah, near Mahableshwar and Satara.

Posted on 1st March 2012:

Mumbai starts the month of March on a cool note. After a stint of very high temperatures, the weather has stabilised. The first day of March recorded a low of 13.4c at S'Cruz and 18.4c at Colaba. 5c and 3c below normal for this day, and the daytime temperature was nearer normal at 2c and 1c below normal respectively. 

Actually, the day temperatures at Mumbai Scruz has yo-yo- ed a lot in February, as is shown in the graph. 
This is a lot of fluctuation for a coastal city like Mumbai, where we do not normally see frequent ups and downs. Though its ok to see a "one time" high of 39/40, the frequency was a bit more in February this year.

But, what is this discussion and blaming the daily variation for various illnesses and sickness ? Are the Mumbaites not able to take a day's fluctuation of 16 degrees and sometimes a variation of 20 degrees ? Or, are we not able to resist some typical Indian weather change ? Why typical Indian ? 

An inland city in central and western India has a normal variation of 18-22 degrees between day and night. Be it Pune, Ahmadnagar, Indore, Gwalior or be it some cities in interior T.N. 
If one sees today's all India city temperatures in the IMD report, we can see at least 20 cities with a day/night variation of 20 degrees or more. And the most variation today is seen at  Ahmadnagar, 28.8c  ! 28.8c is the variation in temperatures between day and night in 24 hrs !! 

I dont think there is so much of "health discomfort" in rural or interior cities of India like we experiance in Mumbai. 

Its got something to do with Mumbai's hygiene and "smog" and pollution conditions. And naturally other basic requirements which may be lacking.

Posted on 2nd February @ 11.20 pm

Note on Mumbai low this week:

Mumbai Colaba recorded a low of 12.5c on Monday morning.Doubtfull, very much so !

Firstly it was less than S'Cruz, which measured 13.5c on the same day.Generally, it is lower in Colaba only in the Rainy season or summer. Very difficult in winter. 
Secondly, Colaba was 16.6c on Sunday morning, and S'Cruz was (again difficult to digest) 10c. Now, on Monday morning, S'cruz rises to 13.5c by 3.5c from the previous night, and Colaba drops 4c from the same night in reference ! Seems a bit "uneven" and hard to digest!

Again, ( dont know if it is important or if this shows any significance to readers, but to me it is a point to consider),I recorded 17.5c on Sunday morning (Colaba 16.6c, S'Cruz 10c), and on Monday morning I recorded 18.4c (Colaba 12.5c and S'Cruz 13.5c). 

Sunday, 31st Jan,  Morning: Colaba 16.6, S'Cruz 10c and my residence ( Brach Candy) 17.5c

Monday 1st Feb, morning: Colaba 12.5c,  S'Cruz 13.5c  and Breach Candy  18.4c.

Posted on 31st Dec @10 am:

31st Evening:
Mumbai: Clear sky, with NW winds blowing till mid night. Calm conditions post mid night, when the temperatures will drop to some extent. Not to expect extreme lows, as seen a few nights ago. Low, minimum, will be 16c at S'Cruz and 19c at Colaba. Remember, the minimumis actually recorded at around 7 am in Mumbai.The first day of the year will be warmer at 31c.
A few nights ago, an unofficially recorded reading mentioned a low of 10.5c at Panvel. Though not official and authentic, I would presume it to be fairly accurate. 31st night would be around 18c , and the morning low would be 14c on New Years day.

Pune: Partly cloudy with high cirrus clouds. Calm night, with a morning low of 14c. Warmer than the previous night.

Nagpur will be partly cloudy and night will be stuffy to some extent.The morning's low will not go below 19c. The day will be partly cloudy, with light drizzle expected in some parts.

Delhi: Getting foggy from late evening/early night hours, and fog persisting till noon the next day.Night will be chilly, with a morning low on the 1st day of the new year showing 7c.Day will be around 21c.

Posted on 26th December @ 10 pm IST

The much awaited NW winds are blowing across the plains of the Indian region in the NW, Central, and the coastal (west).
Good news for Mumbai, which has been thru a "warm" sspell almost with above normal day and night temperatures till 23rd December. Before that date, nights refused to go below 19c at S'Cruz, while Colaba was at 22c as among the lowest. 
Vagaries was receiving queries as to why this is happening, and when will Mumbai actaully see a reasonable drop ?

A write up answer was put up on 20th Dec, and explained that all regions of Mah. except the Konkan coast was feeling the winter drop in temperatures.It would be pertinent to recall that vagaries had mentioned, with the help of a forecast map (for the 22nd to 26th period), that on resumption of the NW winds from the 23rd, the Konkan coast would cool down.

Since the 25th, the NW winds have started sweeping the Konkan coast, and Mumbai feels the difference ! The lowest at S'Cruz on 26th was 15c, and Colaba saw 19c.26th saw a reasonable high of 29.8c at Colaba, and S'Cruz was at 30c in the day. 
This article is published on the 26th evening, but will be read on the 27th, by then I am sure of S'Cruz seeing 14c and Colaba 18c.

In the 10 day forecast (dt:18th Dec), Vagaries had mentioned of an odd night going down to 14c by the 30th of December.
Quote and reproduced from 18th blog:"From the 25th to the 31st, I expect the nights to drop. Not too much, but to around the 15c level, with an odd night at 14c, at S’Cruz, and to the 19c level, with an odd night at 18c for Colaba".

Forecast:27th Tuesday : Clear skies. Strong Nw winds in the evening. Night temperatures will be around 14c at S'Cruz and 18c at Colaba.
28th Wednesday: Clear skies. Strong NW winds from evening. Day and night range will be between 31c - 15c at S'Cruz and 30c - 19c at Colaba.
29th Thursday: Partly hazy sky with high clouds. Day will be 31c. while night will rise to 18c at S'Cruz and 21c at Colaba.
30th Friday: Hazy with high clouds. Day and night range same as Thursday.

Pune forecast:
27th Tuesday and 28th Wednesday: Clear sky.Night temperature will remain around 10c.
29th Thursday: Hazy sky with high clouds. Night temperature will be at 11/12c.

Nagpur will get cloudy skies from Wednesday, with rise in night temperatures from Wednesday.

Posted on 1st December @ 11.30 pm:

Mumbai has been too hot in the month of November. Though the average was 1.13c above normal (see diagram above), it seemed much more, and was the highest in Asia on several days of the month.2 days saw 37c, though not the highest ever, it could well be the highest average ever for the month.
Reason: Initially constant NE and E breeze, restricting the sea breeza (W). Then, a few days slight relief from the W.D. which brought the S'Cruz night down to 18c. But for a couple of days only, as AS-4 swept in and brought in the moisture and clouds again.

Mumbai S'Cruz Forecast for the weekend:
Friday: Haze with high clouds. Temperatures 34c - 22c
Saturday: Clear. Temperatures 33c - 22c.
Sunday: Clear. Temperatures 33c - 21c.

Pune too was hot, though above by 0.57c.(see diagram). Much better, as for a week or so, the city had lows of 10/12c for a few nights. But the temperatures rose again, as the clouding rolled in.
Pune Forecast:
Friday: Temperatures 32c - 17c.

Chances of Rain for Mumbai from AS-4..are  diminishing and moving away !

The morning’s (9.0am IST) rain image shows the rain patch of the system “shrinking” and at the same time moving away from Mumbai…
However, observe the forming  “eye” of the storm

Just check this temperature diagram for Mumbai S'Cruz.
It is for the period just after the post monsoon rains abated. The day's high is a steady line at 35c, and the minimum started dropping a few days ago. The average temperature for the 1 month period in question is 0.86c above normal. That is the mean temperature considering the max and min.

This graph is for the current week from the 15th November till date.

This is one of the longest period of max temperature hitting 35c or more for 16 days at a stretch in November ! In fact, un officially I would put it for any month ! During this period the city saw a very low humidity of 19% on a particular day !
Monday was again at a high of 36.2c at S'Cruz and 35.6c at Colaba.

The highest ever for November on record is  37.4c in 1979 for S'Cruz, and  38.4c in 1978 for Colaba.

As explained, an anticyclone which normally has clock wise winds, has resulted in E/NE winds blowing over the west coast of India. This brought hot dry inland winds over the coastal belt, and delayed the setting of the the “cooler” sea breeze.

Mumbai Forecast:

Sunday, 16th October:  Clear morning. Like Saturday, thick dark cirrus clouds (anvils from thunderheads) will cover the sky from the east by 6pm. (For Mumbai). Light rain in eastern suburbs or some parts. Rain amount  upto 5 mms in certain areas. Day temperature 32c. Stuffy night.
North and NE Mumbai had a thunderstorm of medium intensity on Sunday night. Starting generally after 8 pm, extreme South Mumbai had no rains at all. Mahalaxmi area received 12 mms, and various centres up to North Mumbai between 5-15 mms. S'Cruz station confirms 26.5 mms till Monday morning .
Vagaries' had estimated some late rains (after 6pm) on Sunday,upto an average of 5 mms. City received an average of 10 mms from 4 centres readings taken. Generally rains from these types of anvil TCs which come late are less in quantity.
Monday forecast remains valid as given today (Sunday) at noon.

Monday, 17th October: Clear/hazy morning. Patches of clouds developing by evening. Stuffy night.

Pune could see development of thundery clouds on Sunday. Rain likely in some parts, amount could be around 20 mms. Monday could also see some thundery developments, but to a lesser extent.
Rainfall decreasing after Monday, as SWM withdraws from S.Maharashtra after Monday.

Posted on 13th October@ 3pm.

The conditions of SWM withdrawal towards Maharashtra started from 30 th Septeember.

On 30th. itself, as if in a sudden rush to retreat, we had discussed, the "widhrawing" ridge having shifted into Maharashtra, and came down South more than expected. This had brought clear skies and hot weather into Maharashtra in the first week. 

Hoping this to be a temporary downward shift, it was expected the ridge to move back to the North, and allow the retreating SWM to soak with the thundershowers in Mah and Mumbai. Helpfully, a UAC formed in the Arabian Sea off Mah coast, and reveived hopes of some farewell showers.
Vagaries had, reluctantly given some hope for week end thunder for the first week end of October for Mumbai. 

Without showing much hope, the UAC vanished, and allowed the withdrawal to resume. In the first 8-10 days, city had sprinkling of light rains scaterred in different areas.There was only a 30% chance put up by Vagaries for Mumbai on the 7th. 
International models also maintained a dry run for the city.

Today, we have the internet and a close follow up of weather events and developments. A few decades back, 10 days of clear hot weather with risnng temepretures would have drawn its owninference of SWM withdrawal. and a "post monsoon" shower would have been registered yesterday.

As the withdrawal picked up South of Konkan, a spurt of heavy thunderstorm activity commenced from Tuesday in South interior Mah. And continuing on Wednesday. Some of these thunder heads rolled into Mumbai and brought violent storms with heavy rains.
Aggrevated by strong west 200 mb jets and heat, convection was at its maximum over the heated land mass.

Negative wind shear since last 48hrs, and now at 60 knts, will keep the upper atmosphere unstable with divergence. Seeing the negative shear, unstability in the interiors and along the ghats is likely to hold on for the next 72 hrs. Thunder cells developments along ghats and periphery expected today. Severe storms expected in Southern Maharashtra.
Capacity expected to diminish after Saturday.

Thunder clouds can roll into Mumbai today. Intensity could be less than yesterday, and may be in parts.Diminishing from Saturday.

Posted on 1st October @10.20 pm:

Vagaries would remove the SWM from the "dark Blue " regions shown on the UTH map, barring the NE states. (Please note: UTH map is not the sole indication of SWM withdrawn areas. this indication is used today to make it easy (on map) for vagaries to explain the SWM retreated region). 

Saturday, and we see the SWM retreat line just South of the Maharashtra's Northern boundry. OLR and UTH are favouring fast withdrawal, however there is stiff resistence from the dominationg 200 mb winds. Even water vapour content is low above the 20N line.

Meanwhile some showers in N.I.Karnataka on Saturday. Bhavikere 45 mms, Neveli 38 mms,  Gadag 31 mms, Chickmanglur 29 mms, Dharwad 23 mms. 
Parts of Pune had light showers on Saturday.

Thane has received 3088 mms , Vasai 2816 mms and Talasari 3223 mms till end of September this year.


Posted on 30th September @ 10.30 pm

End September, the officially calculated date for SWM withdrawal for Mumbai. But Monsoon has not retreated, and expected to be here another couple of days.

Weekend Thunder Rain is possible.

Rainfall for September, and the season's total
Colaba: 355 mms (September) and total 2879 mms.
S'Cruz : 275 mms and total 3155 mms.
Average for September works out to 315 mms. 
Vagaries (see 1st September posting on this page) estimated 300-350 mms.

Amongst the lakes supplying water to Mumbai, the highest rainfall for this season was recorded at Tulsi, 4526 mms.

The combined storage of all lakes as on 30th Setember is 12.80 lmlitres, against a full storage capacity of 13.0 lmlitres. (98.48%). 12.80 lmlitres would mean 13 months stock, as per consumption rate today.
Last year, as on date combined storage was 12.82 lmlitres (98.67%).

My comments on your  observations on the absolute current weather in Mumbai.

No, Junaid, there is no anti-cyclone slipping into Maharashtra. In fact, today, there is no "solid" anti-cyclone over the NW too. There is a ridge from Rajasthan down to Maharashtra.

It may be recalled, that vagaries had earlier mentioned of this ridge dipping into Maharashtra from the North. This was preventing the thunder cells (normally on the scene over the region) from forming over interior Mah. Today, I see the ridge prominently persisting down South to Goa
In fact, the well formed ridge has established over the Maharashtra region, causing clear skies.

In effect, it could easily mean that sliding down of the ridge could well mean a retreating SWM. A SWM retreating up to Maharashtra could safely be construed looking at the 850 mb charts today.

But, this being the lone parameter against an established SWM, the other parameters like on-going rainfall (however scanty) in different regions of the state, Upper Troposphere Humidity, 200 mb jet streams and OLR are still in favour of clinging on to the the SWM.

Scattered thunder heads had developed in interior Mah.on Monday also. Aurangabad received scanty rain today, with lightning in the Southern horizon. Overnight, Matheran again had 1 cm of rain while Lonavla had 1 cm with distent thunder in the vicinity.

The good news ! There is every probabilty of the ridge shifting back North towards M.P.again, albiet temporarily. This could give a chance for the end -of -the -season thundershowers to form and give a thundering farewell to the state and Mumbai.

Of-course, this unusual course of weather events may push the SWM withdrawal from Mah. and Mumbai date by a week, that is in the first week of October.

I would put up an arguement like: in the event of other parameters still being pro-monsoon, why did the ridge moved an extra bit south ? Then it is unpredictable to say when it would go North again.

In the unlikely case of the other 3 parameters mentioned above "catching up" with this region, before the ridge moves North, then it would be imperative to withdraw the SWM from Maharashtra, as all conditions would get fullfilled.


Posted on 21st September:

Now, this was the forecast put up on Vagaries on Monday.(Still Valid).
On 3 or 4 days (some days) from Tuesday thru Saturday, there is a
Possibility of advent of thick strato-cumulus clouds (restricted to morning hours) forming over parts of the city. This may lead to some brief morning showers in restricted areas.Day will be hot at around 32c.
Later, thunderclouds may form and drift over parts of the city by evening, briinging showers.

There was some confusion, as I got a few mails, it was not explained correctly.
It needed some clarification. 
Forecast indicated that on some days from Wednesday thru Saturday, Mumbai would experience the weather conditions sequence mentioned in the forecast.

Today, Wednesday, was one of the days. Mumbai received some morning showers due to advancing strato-cumulus clouds from the East. Later after a brighter afternoon, some heavy showers again in the evening, coming from cumulus clouds, and thundercells, formed due to convection.. Rainfall at Colaba was heavy, with 22 mms recorded till Wednesday evening. 

Wednesday, 22nd, Thru Saturday,25th: Partly cloudy day. Thundershower in the evening on some of these days.Days will be a bit warmer at 30c. Night temperatures to fall to around 19c from Friday.

Posted on 3rd Saturday @11.45 pm
South Mumbai had a couple of sporadic (but scattered) heavy showers early Saturday morning. Showers have been reported from some Northern suburbs from late morning.

Cmdr Potey reported a shower on Friday night with thunder and lightning. That was due to the thunder cells which had developed in the evening (mentioned in vagaries earlier). 
svt says of thunder today also. This is due to favourable LI, with cloud height at 9 km, though a "head" is seen going upto 12 kms just south of Mumbai.

Colaba received 23 mms in 24 hrs till 8.30 am Saturday, and  mms and S'Cruz measured 39 mms in the same time frame. 
In the next 3 hrs, till 11.30 am Saturday, Colaba received 8 mms and S'Cruz also 8 mms.

Posted on 1st September@11pm

Mumbai's 2 weather stations normally receive an average of 280 mms of rain between them in the month of September.

I would estimate variable amounts of rainfall till the 9th (give and take a few days. MJO cannot be as on exact date). a dull period could follow up to the 22nd, after which Mumbai can get the evening thundershowers. A sign of withdrawal.
Expect the SWM to be totally withdrawn fro Mumbai by around the end of this month.

City can get around 300-350 mms this month on an average.

Thursday morning was bright and sunny. After 11 am, the skies were overcast, and city received showers, at intervals till the evening. Thunder was also heard. 
Rain amount during the 24 hrs (Thursday Day/Night) was 51 mms at Colaba and 36 mms at S'Cruz. Average 43 mms. Vagaries estimated 30 mms.
Friday Mumbai will see frequent showers, some heavy. Intervals between showers could bring a sunny break.

Thane has received 2861 mms till 31st August this year. Last year's rain till date was 2781 mms.

Weekend forecast for Mumbai, Pune and Nagpur will be up tomorrow.

Saturday: Clear morning, getting cloudy as day progresses. Thunderclouds could develop in the eastern and northern horizon by late afternoon. A few light showers in the day insome areas.
Sunday: Development of thunderclouds by late afternoon. Light to moderate rain by evening with lightning.

Expecting thundershower in Lonavala and Mahableshwar on Sunday evening.

Posted on 16th August:

Mumbai has been getting negligible rains , say up to 10 mms per day from Sunday. Axis running away north and monsoon in a supressed phase being the reason. 
As svt asks, will Mumbai get the estimated 600 mms for August ? 

Well, this lean phase from 5th to 20th August was expected, as mentioned in our Mumbai page on 30th July, and what we have to see whether the remaining days of August covers up the deficit of some 400 mms. 
What we would need is another system to cross into Mah. from the Bay. This can happen once the conditions return to the normal required, like axis shifting down southwards, and active MJO conditions, for "in situ" systems formations in the Bay.

The Lakes combined storage level today is 9.68 lmlitres, against 9.88 lmlitres last year as on this date. The total storage capacity is 13.0 lmlitres.

There are reports of some very heavy downpours from South Gujarat coast today. Rain amounts are awaited.
Forecast put up yesterday for Sunday night and Monday/Tuesday holds good.

Mumbai rainfall till July end (2 months):
2011: Colaba 1746 mms, S'Cruz 2025 mms
2010:    "       2046 mms     "      1962 mms

With the west coast off shore trough activated, the heaviest rainfall was recorded at Panvel, 31 cms. Embedded with a deep vortex off the Konkan /Karnataka coast, it was able to precipitate heavy rainfall all over Konkan, and fairly good rains on the Karnataka coastline. Kozhikode received 7 cms. 

Its a one-off situation. The monsoon axis is almost at its normal position, No UAC over Gujarat, or in the interior. Nothing exactly ideal for formation of such vortice. But they are there. Activation to some extent was expected Friday/ Saturday, but, i had given a maximum rainfall up to 10-15 cms in pockets. But, the actuals in the hinterland was much more. almost like a cloudburst in Panvel (400 mms as Junaid said) in 2 days, Uran and Thane. 

Tulsi lake received a bountiful 26 cms. The lakes' actual storage as on 29th morning was 5.67 lmlitre ( Full storage 13.0 lmlitres).

Mumbai colaba recieved 63 mms and S'Cruz measured 90 mms during the day Saturday, upto 8.30 pm. 
Vagaries forecasted "rain decreasing after night" for Saturday. I would maintain a slowing down of the rain overnight from Saturday, as conditions are conducive for a decrease. Diminishing gradually in the night.

Talking in terms of amounts, Saturday day saw around 75 mms (average) rain in the day, and we can expect another 40 mms at night 

Sunday would be frequented by heavy showers, but lesser than Saturday, and spaced out. Brighter intervals in the afternoon. Sunday can expect a rain amount of 35-40 mms.
A further decrease from Sunday night, and Monday/Tuesday will be cloudy with bright intervals, and a few showers, amounting to 25 mms.

Posted on 30th July @10 am

Friday 29th , Mumbai Colaba received 63 mms rain and S'Cruz 73 mms ( 24 hrs ended 8.30 am Friday). Average 68 mms, Vagaries estimate 70 mms.

Posted on 29th July @10 pm
Mumbai Colaba rainfall till Friday Morning: 66 mms and S'Cruz 98 mms average 82 mms. Vagaries estimate  (day and night) was 50 mms. 

Posted on 26th July:

Why the surprise about a heavy shower in Mumbai ? Got a few direct e-mails asking about the "origin" of the rains etc ?

Showers were more concentrated in central Mumbai. Colaba recorded 7.6 mms and a max temperature of 30.6c till Tuesday night, and S'Cruz 16.2 mms and 31.5c. Here at Breach Candy I measured 23 mms.

That's what vagaries had expected. Vagaries forecast for Tuesday mentioned :"Partly cloudy, with a few heavy showers in some areas. Sunny intervals will make it reach 31c in the day. Rain amount  20-25 mms." 
Well, Tuesday evening, some areas did get a 45 minute heavy shower, while it was less in some other parts of the city.
Wednesday forecast is also maintained as given yesterday: " cloudy with sunny spells. 3/4 showers, a few heavy downpours in parts of the city. Rain amount 20-25 mms."
A few overnight could be heavy in some areas.

Shall await the behaviour of Monsoon axis and put up next forecast tomorrow.

Posted on 19th July:

After the sudden rainy Sunday, 17th, morning, which poured 106 mms till 8.30 am Sunday, most of it after 3 am Sunday, it was decreased precipitation on Monday/Tuesday.

Monday /Tuesday witnessed frequent heavy showers, inter-sparsed by bright, and sometimes sunny intervals. The showers were not too long to cause flooding hassles, and not too short lived to take temporary shelters. Keeping Mumbaites in a typically July monsoon mood.
Monday measured 25 mms at Colaba and 42 mms at S'Cruz, averaging 33 mms. (Vagaries' Monday estimate: 30-35 mms).
Tuesday measured 38 mms at Colaba and 62 mms at S'Cruz. average 50 mms. (Vagaries estimate: less than 35 mms).

Wednesday 20th: Inter-sparsed showers, some heavy. Bright intervals in between. Rain amount  average 35 mms.
Thursday 21st/Friday 22nd: Fewer showers, though cloudy conditions. More sunny intervals Rain amount  average 25-30 mms.

Posted on July 15th:
Yes, reduced rainfall in Mumbai on Friday. With S'Cruz and Colaba both measuring 5 mms during Friday (15th), we may expect another 10 mms at night to make the 24 hrs tally reach about 15 mms. Nana Chowk area measured 15 mms during the day. Most other AWS stations in Mumbai measured between 4-12 mms on Friday.

Saturday/Sunday: Sunny intervals, with passing showers. Sharp showers and may seem to last long, but ending abruptly. Rain amounts  20-25 mms per day.

Pune for the weekend: Cloudy, with sunny intervals,and drizzle rains in some parts.
Nagpur: (Refer yesterday's blog for Friday). Thundershowers will clear after Friday. As mentioned yesterday, weekend will be cloudy, with clearer nights. Drizzles in some parts.

Please re-read the article below on Mumbai Page (30th June) as prelude of this review.

Reviewing July's progress, Mumbai Colaba has received 433 mms and S'Cruz 679 mms. Average 556 mms till July 15th. Equaling June's total rainfall average. Vagaries has estimated an average of 750-800 mms in July.

Lakes are around 50 % filled to capacity. Exact levels of 2 lakes are not available with me.
Hence, taking 50%, we have a storage today of 6.5 lmlitres. That is approx. 6.1 months stock, 183 days.

Mumbai City June and July 2011 Scenario:

Now, as per Vagaries' MW assesment, Mumbai saw the arrival of the SWM by the 9th of June.

Against a normal June rainfall of 585 mms,vagaries predicted around, 550-600 mms in June. Well, the June figures are here. 
Colaba received 461 mms and Santa Cruz 662 mms. Large variation of 200 mms between the 2 stations. Taking the average, we have 560 mms !

Previous Year's June rainfalls at Colaba and S'Cruz resp: 947,712 (2010),  266, 216 (2009),  736,801 (2008),  803,750 (2007),  430,480 (2006).

July could see a couple of prolonged continous heavy spells. I would expect around 750-800 mms in July, against a normal of 750 mms. 

Here, we take into consideration 2 systems to come from the Bay. Both,if, affecting the west coast, Mumbai can get (the systems being normal and takin a normal track), about 175-200 mms from each system over 2/3 days. Thus these 2 spells could be expected between the 7th and 25th of July. 
Without a "break monsoon", normally Mumbai showers on a monsoon day could measure upto an average of 25 mms per day, so we can expect another 400 mms at least for the rest of the month. 

NT,svt,emkay,Pradeep and ananth, and others, please contribute your July rain estimate for Mumbai on my mail. Would like to put up on vagaries' interaction page for readers to share.

Lakes Position: 3 out of the 6 lakes supplying water to Mumbai have received more June rainfall as compared with 2010. The 3 which are less than last year are about 33% less than 2010, and the excess 3 are about 15% more.

The full useable water storage capacity of all lakes is 13.0 lmlitrs. End June 2011 fill up is 1.61 lmlitrs, and end June 2010 was 0.61 lmlitrs.

Monthly requirment for Mumbai: 1.02 lmlitres. Today's stock: 45 days.

My estimate is that, as explained, lakes should get their normal rainfall in July.

Taken from my car at Breach Candy on Tuesday at 5 pm

The thunderstorm in Mumbai on Tuesday afternoon was a typical case of "micro-weather". Thundercells built up over the city in the afternoon, and cloudtops reached a height of 12 kms. The hot humidity helped it grow. The cloud tops temperature sat. image of IMD did not reflect this storm since it was too small and negligible.
The cell precipitation was restricted to a very limited area, from Santa Cruz in the North (16 mms) to Colaba which received 13 mms of rain. It was particularly violent in Worli/tardeo and Malabar Hill areas. Water logging was witnessed in Tardeo and some South Mumbai spots, where unofficial rainfall reading was 29 mms upto 5.30 pm. Readers point out that there was negligible rain in Andheri/Kandivali and Thane. Thane measured only 3 mms of rain. 
The thunderstorm will not effect nor have any change on the overall situation, for Mumbai or Mah, discussed yesterday. 
Mumbai's forecast holds good, of decreasing rainfall from Thursday.

Posted on 30th. May, 10 pm.

A report inToI (Monday) reads of Colaba having warmer days than Santa Cruz this summer. Its a fact! Some some reason, the Colaba readings are more than S'Cruz, especially in the day, and thats not normal. The average day at Colaba this May has been at that with S'Cruz at 34.0c...Not usual, but cant say why !
In fact, if you remember, Colaba has also been keeping up with the rainfall in 2010 with S'Cruz. Again not normal. 

The S'Cruz temperature diagram for May says it all...Whatever one might say, its been a tolerable summer with average temperature around normal.

The overall summer estimate put up by vagaries in end March reproduced again for ref.

 Slightly below normal along the west coast and normal in most of the regions barring west Rajasthan and extreme North.

Coming to Mumbai weather, seems the summer season is in its final week now. With the SWM likely to hit Kerala tonite, and normal progress estimated up the west coast, Mumbai should get SWM by the 10th of June.

Accordingly, seeing the moisture creep up with the SW winds, pre-monsoon showers will cool the city from Thursday, 2nd of June. Gradually increasing to eveining thundershowers from Saturday, 4th June.

A fair wetting of rains this weekend could be estimated at 15-20 mms Thu thru Sunday.

                             31st, Tuesday/1June,Wednesday: Partly cloudy with thunderheads in the eastern sky by evening. 

                  2nd June,Thursday/3rd June Friday:Partly cloudy to cloudy. Thunder clouds in evening. Sharp drizzle /showers in some parts . Rainfall upto 5 mms.

      4th June, Saturday: Partly cloudy. Thunder clouds by afternoon. Sharp thundershowers in the evening .Rains up to 10 mms.

Posted on 30th morning: 
Parameter not confirming full SWM advance yet.Also see winds (at NW) and 200 jet stream.
These are my personal views.

Posted on 15th. May: answer to PWP Query.

As per my records, and information, 3 cyclones have actually struck, and hit right into Mumbai..head on ! 

~1882 – More than 100,000 inhabitants of Bombay were killed when a cyclone in the Arabian Sea pushed massive waves into the harbor.No details available with Vagaries, but seems the deadliest one ! If any details are procurable, please send for all to read.

1st June, 1855 cyclone in Bombay -boats destroyed at Appollo Bunder [lower picture]. An article titled "Cyclone in Bombay", apperead in the "Illustrated London News" dated 24th June 1885.  The picture also shows the article.

18th - 21st  November, 1948..Crossed coast near Virar, 72 Km. North of Bombay (Mumbai) at about 0830 hrs. IST on 22 November. Maximum wind : Colaba recorded 120 kmph (65 kts) and Juhu recorded 151 kmph ( 81 kts.)

Posted on 13th.May @10.30 pm

Mumbai Weather Outlook:

34c - 27c. 

This is the current temperature range experianced in Mumbai. And I would say that's normal for this time, .
A humidity ranging between 60% and 74%, has been the trend in the city for the last 10 days now.

May 2011 is normal. With cumulus clouds drifting throught he skies, and a NW wind keeping the evenings just about manageable.
In fact, the weather last 30 days through mid April has been just about normal. 
Diagram put shows a miniscule rise of 0.07c. 

There has been no rainfall yet from March in Mumbai. But that too is ok. 
The city has had many April/Mays without a single mm of rain. And it has no bearing on the SWM rains later.

The wettest May, as far as my records show, has been in 1918, when the city (Colaba) was drenched with 279 mms. By coincidence, 1918 was a drought year in India, with one of the lowest avaerage rainfall on all India basis. 65 cms, against a normal of 89cms. That is -27%. Absolutely a severe drought year.

The wettest May at S'Cruz was in the year 2000, with 388 mms of rain.
Mumbai's (Colaba) last 5 years' May rainfall has been: 2010=0 mm, 2009=2 mms, 2008= 0 mms, 2007=1 mm, 2006=135 mms.
of rainfall.

For the remainder of May, I see the temperatures going in the 35c - 29c range. Expecting some increasing cloudiness from 19th, indicating a rise in the night temperatures.

The highest ever night temperature for Mumbai I have on record is 30c. There is no official record available to confirm the highest minimum in Mumbai.

Skies will be partly cloudy. Morning skies will start getting cloudier with heavier cumulus clouds after the 20th. Thunderheads will pop up in the east around the 20th/21st. Possiblity off light rain in some areas. Mumbai forecast till the 17th of May has been put up. Will update next 4 day forecast for Mumbai on Tuesday.

However, pre-monsoon thundershowers would commence in the Lonaval/Pune/Khandala hills by the 25th of this month. Expecting Mahableshwar to get its first pre monsoon showers by the 25th of May.

Pune could, however see some thundery developments, with rain in some areas, on Monday, 16th, evening.

For Mumbai, I would like to maintain my previous estimate of monsoon arrival dates.
Much awaited regular Pre- Monsoon evening thundershowers could cool the city from around 3rd/4th June. Regular Monsoon set could be around the 9th/10th of June. Expecting initial commencement to be sluggish.

Quantum forecast for the city for June and July has been put up earlier.

If need be, situation could go in for some revisional changes, depending on the developments. This is the synoptic situation as on today.

What's the Monsoon scene for Mumbai ?

After a scorching initial March heat up this year, Mumbai has "cooled" down, and thru April was around the normal temperature range. Diagram for Mumbai temperatures for April/May shows the normality thru April/May (upto 5th).
May too began on a moderate note, with days around 33/34c and nights at 26c. Quite ok i would say. Humidity still has some scope to rise.

A dry April and May is not unusual for Mumbai. Mumbai region usually gets its pre-monsoon thundershowers about 7 days before the onset of the monsoon over the city.

The dates of onset for the last 5 years in Mumbai have been: 2005 - June 19, 2006 - May 31, 2007 - June 18, 2008 - June 7, 2009  June 24 and 2010 - June 14.
Quantums of actual rainfall has varied, and is in no way connected with the dateof arrival. 

The highest rainfall ever at Colaba was in 1954 when 3482 mms was measured (2010 saw 3347 mms) and the lowest was in 1904 with 849 mms. At Santa Cruz, the wettest year was in 1958 when the rain guages measured 3785 mms with the all time low being 1481 mms in 1968.

Month of May this year may continue in the 34/35c range, not really going beyond that. But with the humidity expected to rise, the latter half of this month should be sweaty and uncomfortable. Coudy weather after mid May will add to the dis-comfort.

Now, as per Vagaries' MW assesment, I think Mumbai should see the arrival of the SWM by the 11th of June. 
By theory, this means the pre monsoon thundershowers should start by the 4th of June (give or take a day).
Initially, it seems, the SWM in Mumbai will not see a "real" pick up, and thundershowers will continue to "totter" till the 20th of June. Can pick up into prolonged spells of rains after the 20th. 

Against a normal June rainfall of 585 mms, I would predict, around, 550-600 mms in June.

July could see some prolonged continous heavy spells. I would expect around 800 mms in July, against a normal of 750 mms.

Mumbaites, please contribute with feedbacks and your opinions.

The rise  in Mumbai's day temperature today (Monday) has not taken Vagaries by surprise ! 
The high in Mumbai S'Cruz shot up to 33c, and 32c at Colaba, overnite from a pleasant 29c last 2 days.

Tuesday: Warm at 34c with East breeze blowing.

Posted on 19th. Feb at 1.00 pm 
Mumbai doing well and  Vagaries' Forecast maintianed.
Thursday /Friday went of fine with the day at 30c and with a minimum of 20c at Colaba and 17c in the Suburbs.

Monday is breezy at 19 kmph winds in the NW direction. Cool and pleasant at 28c at 1 pm. Humidity also low at 40%.

Posted on 16th. Feb @ 11 p.m.

For Mumbai, clear skies from Thursday, 17th. Feb. 

Thursday/Friday: Clear with temps in the 31c - 20c range.
Saturday/Sunday: Windy with N breeze and cool day. At about 29c, it will be pleasant and with lower humidity, it will feel more comfortable.

Monday: Rise in temperatures.

Posted on 16th. Feb @ 9.30 am:
Just as I am writing this post, it has started to drizzle here, in Breach Candy, South Mumbai. Reports of morning drizzle has also come in from the western suburbs like Ville Parle.
The weather has "accepted" Vagaries' forecast made on 11th. Feb (also see Home Page) with Mostly cloudy and overcast conditions in Mumbai since Wednesday morning.
Presently at 24c, its pleasant and should high at 29c, and then Mumbai should follow the forecast schedule below (11th. Feb).

Posted on 11th. Feb:
Mumbai weekend skies will be clear and sunny weather, the sharp sun supporting a warmish day (32c). 
But after Tuesday, 15th. Feb, say latest by Wednesday, the skies will start getting partial cloud cover, thus cooling the days to some extent early next week (29c). 
After Wednesday, the disappearing clouds  could cool the nights to around 16c in the suburbs and 19c at Colaba.

Pune and Nasik could see 9c, and Mahableshwar will have pleasant days next week at around 26c.

Posted on 10th. Feb:

In Mumbai, after the days retained back the 29-30c level, the nights too have come back to the 16c-20c range. This was estimated in vagaries after the torcherous day when it touched 36.7c at Colaba, last week.
However, this range might just go up a degree or two till the weekend. After the F2 effect, I see the temperatures dropping back to 15c-18c range at the weekend, around the 13th. of February.

Posted on 7th. Feb:

Mumbai temperatures have dropped back to 30c at Colaba and 31.8c at S'Cruz. Vagaries was expecting an immiediate relief from the "un-earthly" 36.5c a couple of days ago.With the minimum at 17c and 21c, both the Mumbai weather centres can expect more drops in temperature next 2/3 days.

On Friday, when the TOI reported the 36.5c, it carried a report quoting the weather bureau as saying." the temperatures in the city will go on rising every day till it reaches the summer normal" ??? Can someone explain this statement ??

Mahableshwar has shot up to 31c, (+5c). Thats the normal mean (day) temperature for April. For the month of May, normal mean (day) is 29c. However, the highest ever in February for Mahableshwar is 33c, recorded on 22nd in 1976.But the low at 14c, is normal for this time of the month.

Posted on 4th. Feb:

Mumbai Colaba day temperature drops to 32.2c from Yesterday's very high 36.7c.
Anyway, as mentioned in Vagaries, temperatures are expected to cool down this weekend, and with the East breeze "absent"today, Mumbai had N to NW winds from the afternoon, thus the welcome drop.

Posted on 2nd. Feb

I think Vagaries "spoke" too soon. Praised the cooler climes of Mumbai just a few days ago...and see now...
Totally Unpredicted ! Mumbai day tempeature jumps to 34.6c at Colaba and 35.7c (+5) at S'Cruz on Wednesday, 2nd. Feb !

As informed on the home page today at noon, the E winds commenced suddenly at around 11.30 am and were the cause of this sudden unusual rise in the day temperatures.
With the W.D. in force from Thursday, we can expect the days to come back, first to normal by Friday, and then below noraml days and nights from Sunday.

Mumbai Weather this January 2011:

Call it GW or the warmest year. Call it, as the TOI put it on 29th."its going to get hotter in India."
But, its been definitely cooler and a very pleasant January 2011 as far as Mumbai is concerned. 
Mumbai citizens would pull out their woolies, if just to showoff, when the mercury bottoms 18c, and would take a cool breeze in the face if the Northerlies have a combined wind chill effect of 18c.

  October 5th.. Dussehra wishes to all Vagaries Readers  It now seems we may have to neglect the weak BB 14 and concentrate on this new Low....
