Mumbai

Mumbai sits on India’s western coast at 19°N latitude, giving it a tropical wet and dry climate. The city experiences three seasons: a hot, humid pre-monsoon summer (March to May), a drenching monsoon (June to September), and a warm, dry winter (October to February). Mumbai receives 2,258mm of rain annually, nearly all in the four monsoon months. July alone averages 868mm across 22 rain days , more than London gets in an entire year. Temperatures remain warm year-round, with winter lows rarely dipping below 16°C (61°F).

The best time to visit is November through February, when the monsoon has cleared, humidity drops to 62 to 65%, and daytime highs of 31 to 33°C (88 to 91°F) are balanced by cool nights of 17 to 21°C (63 to 70°F). During these months, rainfall is near zero and you get 260 to 270 hours of monthly sunshine. The months to avoid are June through September (monsoon, flooding, disrupted transport) and May (peak heat with 71% humidity and heat indices above 40°C/104°F).

Mumbai is India’s financial and entertainment capital, home to 21 million people, the Bombay Stock Exchange, and Bollywood, the world’s most prolific film industry. The city occupies a narrow 22km peninsula, with the colonial-era core in South Mumbai (Colaba, Fort, Marine Drive) and the modern commercial and residential heart in the western suburbs (Bandra, Juhu, Andheri). It is India’s most cosmopolitan city, its most expensive, and arguably its most rewarding for visitors who embrace its intensity.
