Pune Sizzles: Hottest And Driest First Half of June Since at Least 2014 at Shivajinagar

 The avg. maximum temperature at pune shivajinagar in june 2026 1st half is 36.6c. 

This is the hottest 1st half of june at least since 2014.


No rain occured in Pune Shivajinagar in 1st half of June. For the 1st time at least since 2014, that June 1st half of Pune went completely dry. Yearwise 1st half June total (mm) as follows
2014: 10.1
2015: 80.4
2016: 35.2
2017: 88.1
2018: 61.9
2019: 41.5
2020: 112
2021: 57.4
2022: 28
2023: 20.4
2024: 231.0
2025: 132.9

2026: 0

Let's give credit to Delhi AQI when it's due.. Not just criticising always **↓


                                              ** ↓
The reality of today's temperatures in India... With the focus on the Monsoon, the "deadly" heat Wave is forgotten.. The highest temperature in India today is only 42.8°c.. Which incidentally is normal for the station!

 ENSO OUTLOOK:

ENSO-neutral conditions are present.


"Red" SST increase off the Peru coast indicates ElNino formation...not alarming increase in last 4 weeks.

* Equatorial sea surface temperatures (SSTs) are mostly above average across the central and eastern Pacific Ocean. 

*El Niño is likely to emerge soon (82% chance in May-July 2026) and continue through Northern Hemisphere winter 2026-27 (96% chance in December 2026 – February 2027).*


Above Histogram shows intensity of El-Nino getting stronger and effective after August and more after September.

El Niño: characterized by a positive RONI greater than or equal to +0.5ºC. La Niña: characterized by a negative RONI less than or equal to -0.5ºC. 


[El Niño: characterized by a positive RONI greater than or equal to +0.5ºC. La Niña: characterized by a negative RONI less than or equal to -0.5ºC. 

By historical standards, to be classified as a full-fledged El Niño or La Niña episode, these thresholds must be exceeded for a period of at least 5 consecutive overlapping 3-month seasons. 

These anomalies must also be forecasted to persist for 3 consecutive months]

Stronger and effective after August and more after September.

Another aspect to consider:
 In June 2015 too strong El Nino conditions were evolving but why all India rain was above normal in June 2015 with Pune too above normal rain (211.2mm) in June 2015.

Whereas June 2026 also has El Nino setup why all India rain not following June 2015 and is running -26% below normal with Pune 0mm this month so far?


In June 2015 despite evolving El Nino, there was strong MJO propagation in Indian ocean in June (blue line left figure) this enhanced monsoon activity

Whereas in June 2026 MJO is completely locked out of Indian ocean this month one if the factor of monsoon remain subdued so far.
Also 2026 El Nino development is more stronger at this time of year than 2015

There can be other differences too....
 Lastly in June 2015, SOI index value was -12, whereas June 2026 SOI index value already -22. This mean atmospheric response to El Nino in June 2026 is much stronger than June 2015

Maharashtra Specific Monsoon Report:

Due to Image shown, the Monsoon hiatus is prevailing today:


The Monsoon "weak surge" into South Konkan and North Konkan is expected to take a "push" from 17th, resulting in convective thunder showers in scattered areas. 

 

-----------------------------------------------------------

Mumbai Rain this season till 13th June: Colaba 04 mms (-97%)..Scruz 13 mms (-91%).

Rainfall to increase over Mumbai..(not to expect too much ) from17th to 23rd...just about 20-25 mms accumulated depending on the local rainfall...and we can hope to get the Monsoon set in by the 22nd/23rd of June..hoping that the all time late arrival date of Monsoon (25th June) is not reached this year !

Pune will see an increase in rainfall from the 17th and thunder showers in parts of Pune..though not much can be expected ..Monsoon still evasive till 23rd at least. Pune rain this season is 0 mm.

Marathwada: Some local thundershowers expected from 18th..for 3 days...maybe heavy in Southern Marathwada ( Beed, Latur, Nanded,Dharashiv (30-40 mms accumalated) regions.

Sambhajinagar may get 20-30 mms from 18th -21st..

Monsoon evasive till 24th at least.

Farmers' Advice: If the decision to sow the seeds is taken  after 16th, please note that a semi low rain period may follw till Monsoon moves in around 24th/25th. Precautions have to be taken.


मराठवाडा: १८ तारखेपासून.3 दिवसांसाठी...काही स्थानिक ठिकाणी मेघगर्जनेसह पावसाची शक्यता आहे.. 
दक्षिण मराठवाड्यात (बीड, लातूर, नांदेड, धाराशीव) मुसळधार पाऊस (३०-४० मिमी पावसाची शक्यता) पडू शकतो. 

संभजीनगर परिसरात १८ ते २१ तारखेपर्यंत २०-३० मिमी पाऊस पडेल. 
किमान २४ तारखेपर्यंत मान्सूनचा प्रादुर्भाव कमी राहील. 

शेतकऱ्यांसाठी सूचना: जर पेरणीचा निर्णय १६ तारखेनंतर घेतला असेल, तर कृपया लक्षात घ्या की २४/२५ तारखेच्या सुमारास मान्सून येईपर्यंत पावसाचा कालावधी कमी राहण्याची शक्यता आहे. खबरदारी घेणे आवश्यक आहे.

Meteorological note Monsoon rainfall progression over India to halt for the next 10 days; El Nino background conditions strengthening






Plain Language Summary:

-------------------------------------------

After a weak onset and a sluggish start, the summer monsoon rainfall is now heading towards a significant hiatus over the Indian subcontinent during the next 10 days. Numerical Weather Prediction and AI based model guidance from various modeling centers across the globe indicate that the progress of monsoon rains over India could see a temporary halt as the monsoon circulation and rainfall pattern is all set to weaken and dry air advection could take a dominant role. Rainfall is expected to be subdued across the Western Ghats, the west coast, central and major parts of western and peninsular India. This could be a serious concern for the Agrarian community as several parts of India could see a delay in the sowing activities where irrigation is not available. Models although indicate some revival after the 20th of June, uncertainty prevails as of now on the date and pattern of revival. The situation needs continuous monitoring in the days to come with El Nino strengthening along side. 


Scientific Diagnostic Reasoning:

------------------------------------------------------ 

Analyses of the observed global tropical circulation pattern during the past 2 weeks suggests that the Indian summer monsoon rainfall onset phase found itself struggling against a backdrop of unfavorable sub seasonal and low frequency modes of tropical variability. RMM and 200 hPa Velocity Potential based MJO indices indicate that large scale eastward propagating wave saw itself working constructively with the evolving Low frequency ENSO state over the central and eastern Pacific during the past 2 weeks. The Monsoon circulation caught on to some westward propagating mode to help breath itself for a brief period to make some progress, but it could not stand against the other giant suppressing modes and eventually is giving up on further progression (temporarily). Extended range forecast charts indicate the presence of persistent lower level anticyclonic circulation and rainfall anomalies over India, and alongside dotted with some westward propagating equatorial waves in the lower latitudes. VP 200 hPa clearly indicates the strengthening El Nino conditions which could weaken the Walker circulation and hence the Monsoon in the background. The situation overall looks grim and needs continuous monitoring for management and mitigation on the agriculture and hydrological front.

10th June Post:

Monsoon shows slight advance in response to the off shore trough (explained in 9th post).
Weak current Monsoon parameters are observed,,and seemingly advancing into South Konkan soon..

.The Ratnagiri rains 👇
Compiled by Vag,Abhishek Apte

{ Outlook For Mumbai ...quoting yesterday's Post: "Mumbai with a few spells of pre Monsoon thundery showers till 18th can get accumulated 6 days rainfall (varying between Scruz & Colaba ) of 20 - 40 mms average. An isolated Thundershower may give a heavy localised shower.

Hot an humid. Temperature range 35 - 29/30°."} 

Checking on the much discussed current ''hot night " in Mumbai and Pune..


Colaba had the 6th consecutive night of a minimum temperature of 30°.. 6th -11th June..thus, as per vagaries' notes, equalling the 5 nights
 in 2016.
