Weather outlook from 28th May to 2nd June 2026.    
                          
(i) Mumbai Special 


















(ii) Details:
*Kerala awaits SW Monsoon onset...
*North/Northwest regions to get some relief from heat

*Monsoon winds remain weak, with a weaker Somali jet, avoiding hitting Indian peninsula...sluggish progress after Andaman-Nicobar onset. 


850 hPa winds as of 27th May evening.



*The Madden-Julian Oscillation is in a convection-suppressing phase over the Indian Ocean (phases 6 and 7, with RMM amplitude >1), an important factor in the slow progression of the monsoon. 


The MJO is expected to weaken in magnitude in Phase 7 after 3rd June. Forecasts from various weather models show monsoon winds strengthening from June first week onwards. 

*Westerly winds will align over the southern Arabian Sea and are likely to reach a depth of up to 600 hPa around 3rd June (+/- 2 days). 

*This is when we expect monsoon onset over Kerala. 

*Further northward progress of the Monsoon seems to be on schedule as of now. 
We expect monsoon onset in Mumbai around 11th June (+/- 2 days). 


*A strong Western Disturbance (WD) will affect Northern States/UTs from 29th May, bringing dust storms followed by thunderstorms with gusty, damaging winds. 
Punjab, Haryana, Delhi NCR, Uttar Pradesh, Rajasthan and parts of Madhya Pradesh to receive rain/thunderstorms with damaging winds/lightning from 29th to 31st May. 

*The Himalayan region will get thunderstorms and hailstorms, and some snow at higher elevations.

WD trough will drop way south than normal, bringing in rain/thunderstorm chances for Gujarat and Southern Rajasthan during 29th to 31st May.

Hype created and News Circulation by Foreign Agencies about Alleged "Indian Heat Waves"


The actual facts: Actual Fact shows Summer anomaly variations around+_ Degree only.👇
In this article the foreign scientist says pre-monsoon rain over large areas are below normal
 In reality 1-25 May: All india rain 5% above normal
Centrsl india: 23.7% above normal
South india: 19.4% above normal
North india: only 1.4% below normal
 Also avg temps across ~60% of country so far this May is below normal
The highest average may temp for India was in 1921 31.92c and northwest india avg max temp was 39.86c. This May 2026 is not even close to it to say it historic heat.
Forget 1921, even this May will not break 2024 record which is the hottest may in satellite record (since 1980) with avg. Maximum temperature in May 2024 was 31.08c and northwest india it was 38.36c
Thus, there is :NO MASSIVE HISTORICAL EVENT" with respect to summers/heating in this May
The above times article is completely wrong , nonscientific and the editor journalist should be held accountable for publising totally false stuffs.
