Mumbai's Temperature Spikes to 39.2°C Due to Anticyclone—Why Are Nights Still Cool?

Mumbai, India: The city recorded its hottest day of the year on Tuesday, with temperatures soaring to 39.2°C, nearly seven degrees above normal. However, despite the heatwave alert, nighttime temperatures dipped to 23°C, providing some relief.

Why Is Mumbai So Hot?

Meteorologists attribute the heat surge to strong easterly winds delaying the cooling sea breeze and an anticyclone system hovering over Mumbai. The India Meteorological Department (IMD) had issued a three-day heatwave alert from Sunday to Tuesday, classifying a heatwave as temperatures exceeding 37°C for two consecutive days.

Why Are Nights Cooler?

Despite the scorching days, clear skies allow heat to escape quickly through radiation at night, preventing temperature retention. This natural cooling effect keeps minimum temperatures lower despite ongoing heatwave conditions.

The IMD predicts clear skies and a maximum of 36°C on Thursday, with no immediate relief from the heat.
