Mumbai Weather, Time Zone & Travel Guide
Mumbai sits at 19.1°N on India's western coast, giving it a tropical monsoon climate defined by one of the world's most dramatic weather contrasts: a long, dry, sunny season followed by an intense monsoon that dumps over 2,400mm of rain in just four months. India's financial capital and home to Bollywood, Mumbai rewards visitors who time their trip right.
Mumbai Climate by Season
Winter / Cool Season (November–February): The best time to visit. Temperatures hover around 65–85°F (18–29°C), humidity is manageable and skies are reliably clear. UV index still reaches 7–9 — sun protection is needed year-round.
Hot Season (March–May): Temperatures climb toward 95–100°F (35–38°C) with rising humidity and haze. UV index peaks at 11–13 (Extreme). The city feels oppressive before the monsoon breaks.
Monsoon (June–September): Mumbai receives nearly all its annual rainfall in just four months, often in dramatic bursts that flood streets within hours. June and July are the wettest months — always check the live forecast and local advisories before travel.
Post-Monsoon (October–November): The city breathes again — cooler temperatures, dropping humidity and greenery everywhere. October is an excellent time to visit.

What to Pack for Mumbai
In dry season, Mumbai's UV hits Extreme (11+) — SPF 50+, UV400 sunglasses and a wide-brim hat are essential. During monsoon, a heavy-duty compact umbrella and waterproof sandals are the most critical items — Mumbai streets flood fast. A waterproof phone case and dry bag protect electronics. India uses Type C/D/M plugs (230V); a universal adapter and travel eSIM are essential for international visitors.
