Mumbai records hottest October in a decade, temperatures hit 38.2°C

Mumbai, we know that October can be a really sweaty affair, but this time, it's a big deal. The city sizzled at 38.2°C on Monday, October 12, 2026, recording its second-hottest October day after 2015.

While there might be some respite on the horizon, the IMD expects temperatures to ease with wind pattern changes and the anticyclone weakening.

However, the yellow warning is issued for Tuesday, October 13, indicating humid and hot conditions in isolated pockets. The temperature on Tuesday afternoon was recorded at  37.0°C and 34.0°C in the Santacruz region and the Colaba observatory, respectively. 

Mumbai's second heatwave in October

Monday’s hot weather came just a few days after Mumbai experienced another spell of extreme heat on Friday, October 9, when the temperature hit 37.8°C – around 4.7°C above normal. 

Monday's reading crossed that threshold, making the October afternoon feel more like peak summer than the start of the festive season. 

Additionally, the India Meteorological Department (IMD) considers a heatwave in coastal regions when the highest temperature rises above the seasonal average, with a departure of 4.5°C to 6.4°C meeting the relevant threshold. 

October traditionally marks a gentle transition away from the monsoon and into a mild winter – especially significant given the large number of festivities dotted across the month.

It's a month with a packed calendar, festive and otherwise, with not only Navratri, Durga Puja and Dussehra being celebrating across different communities, but also loads of music festivals, exhibitions, and more.
