• Mumbai recorded its highest October temperature in eight years, with the mercury reaching 37.8°C at the Santacruz observatory on Friday, October
• This surpassed Thursday's reading of 37.6°C, marking consecutive days of unusually high temperatures following the withdrawal of the southwest monsoon. The India Meteorological Department (IMD) attributed the heatwave to an anticyclone over Gujarat and adjoining North Maharashtra. A yellow alert for hot and humid conditions has been issued for Greater Mumbai and neighbouring districts. Climatologists expect some relief as the sea breeze returns, potentially moderating temperatures in the coming days.

Impact & Risks

The heatwave has led to discomfort for commuters and residents across Mumbai, with many seeking ways to stay cool in public spaces. Temperatures are 4.7°C above normal, increasing the risk of heat-related illnesses such as dehydration and heatstroke. Vulnerable groups, including children, the elderly, and those with pre-existing health conditions, are particularly at risk. The IMD's yellow alert highlights the need for caution during this period of elevated temperatures.
