Mumbai’s climate is classified as tropical, with three main seasons: summer, monsoon, and winter. Summers (March–May) are hot and humid, with daytime highs often reaching 33–38°C and humidity levels above 70%. May is typically the hottest month. Evenings are somewhat cooler due to sea breezes, but the heat can be intense, especially during the day. The city’s proximity to the sea moderates temperature extremes, but humidity remains high throughout the season.
The monsoon season (June–September) is marked by heavy, persistent rainfall and cooler temperatures (20–30°C). Over 90% of Mumbai’s annual rainfall – more than 2,200 mm – falls during these months, with July being the wettest. Rain can be torrential, causing flooding and frequent travel disruptions, but the city becomes lush and green. Winds are strong, and the sea is rough, making water activities risky. Winters (October–February) are mild, dry, and pleasant, with daytime highs of 28–32°C and cooler nights (18–24°C). Humidity drops, skies are clear, and sunshine is abundant, making this the best time for outdoor activities and festivals. Mumbai enjoys about 2,200 hours of sunshine annually, with daylight ranging from 11 to 13 hours depending on the season. Winds are generally light outside the monsoon, and sea temperatures remain warm (25–29°C) year-round.
