Mumbai, May 28: On Wednesday, Mumbai's Colaba observatory recorded a maximum temperature of 37.8°C, the highest May temperature in the last 10 years. The minimum temperature was 28.4°C, which was also above normal. The second-highest May temperature in the last decade was recorded on May 16, 2024, at 37.6°C.

Meanwhile, Mumbaikars will have to wait longer for rainfall, as instead of the forecast pre-monsoon conditions, the region is once again reeling under a heatwave.

Additionally, the onset of the southwest monsoon, which was predicted over Kerala on May 26, has shown no signs of arrival, thereby possibly delaying the arrival of the monsoon over Mumbai and Maharashtra too.

Heatwave alert issued for Mumbai region

On Wednesday, the India Meteorological Department (IMD) sounded a Yellow Alert for 'heatwave conditions' for the districts of Mumbai, Thane, Palghar and Raigad. The warning is valid till 8.30 a.m. on Thursday, after which the region will experience 'hot and humid conditions'.
