Mumbai Weather Update: Temperature Hits 38.2°C, Second-Highest October Reading Since 2015 As Heatwave Persists

Mumbai experienced a scorching day on October 12, 2026, with the maximum temperature soaring to 38.2°C, marking the second-highest October temperature since 2015. The Santacruz observatory recorded the temperature, which was 5.1°C above the normal reading. The India Meteorological Department (IMD) issued a yellow alert for hot and humid conditions and later upgraded it to a heatwave warning during the day. Heatwave-like conditions were expected to persist on Tuesday, with hot and humid weather prevailing thereafter.

Though a slight respite was anticipated after a couple of days, the maximum temperature would remain above 35°C throughout the week. IMD Mumbai Director Bikram Singh attributed the rising temperatures to wind flow patterns.

Across Maharashtra, Mumbai's maximum temperature on Monday was the third-highest, with Ratnagiri recording the highest at 39.2°C, 7.6°C above normal, followed by Malegaon at 38.4°C, 5.6°C above normal. Experts linked the extreme weather to the early monsoon withdrawal, which raised ground temperatures, and the delayed arrival of sea winds.

On Sunday, the maximum temperature was 38°C, 4.9°C above normal. Experts attribute these severe conditions to the El Niño climatic patterns, which have also contributed to a rainfall deficit this year.
