Mumbai Weather Alert: 5 Shocking Changes as Rain Fades – Prepare for Soaring Heat & Humidity

Mumbai’s brief cool spell is ending as the IMD forecasts rising temperatures over the next six days, with highs reaching 33°C and lows of 25°C. Following record-breaking rains earlier this week, Wednesday saw minimal rainfall (1-17mm) and the withdrawal of weather alerts. While recent days offered unusual May relief with below-normal temperatures, humidity will now intensify. The shift signals a temporary monsoon pause, though dark clouds remain offshore.

Residents should prepare for warmer, stickier conditions—especially during commutes—while staying alert for potential rain resurgences. Use this drier window to check drainage systems, and prioritize hydration as abrupt heat increases pose health risks.

Mumbai Weather Alert: 5 Shocking Changes as Rain Fades – Prepare for Soaring Heat & Humidity

After two days of record-breaking downpours earlier this week, Mumbai caught its breath Wednesday under overcast skies that delivered only light showers. But this pause comes with a trade-off: rising temperatures and humidity are set to replace the recent cool relief, according to the India Meteorological Department (IMD).  

The Shift in Forecast  

• Rain Retreats: The yellow alert has been lifted entirely after Santacruz recorded just 1mm and Colaba 17mm rainfall (as of 8:30 PM Wednesday).  

• Temperatures Climb: Maximums will rise steadily to 33°C by early June, while minimums hover near 25°C – a notable jump from this week’s cooler 27-28°C range.  

• Humidity Returns: The retreating clouds mean mugginess will intensify, particularly during mornings and evenings. 

Why This Matters for Mumbaikars  

• Commute Relief vs. Discomfort: While reduced rain eases flooding risks on Western/Eastern Express Highways, the humidity resurgence will challenge local train and bus travelers. Carry water and wear breathable fabrics.  

• Health Transitions: Pediatricians note such abrupt shifts often trigger heat exhaustion and dehydration cases. Senior citizens and outdoor workers should prioritize hydration.  

• Monsoon Watch: Dark clouds on Wednesday (captured in HT’s photo) confirm monsoon currents remain active offshore. This warming phase likely precedes the next rain surge – monitor IMD updates closely. 

Local Nuances 

The 3.6°C below-normal temperature at Colaba versus Santacruz’s 2.2°C dip highlights how coastal areas may retain slightly cooler conditions. South Mumbai residents could experience marginally less heat stress than western suburbs.  

Looking Ahead 

“This pattern aligns with typical pre-monsoon breaks,” explains former IMD scientist Dr. Vineet Singh. “Ocean winds temporarily redirect rainbands, allowing land temperatures to rebound. But monsoon clouds are merely regrouping – don’t store away umbrellas yet.”  

Pro Tip: Use this drier window to check drainage grilles near homes. Clogged ducts during sudden heavy showers remain a prime flood risk in low-lying areas.
