Mumbai is India's financial capital and the capital of Maharashtra state, a peninsula city of colonial Gothic architecture, Bollywood studios, and one of the world's busiest commuter rail networks. The Gateway of India and the Arabian Sea promenade of Marine Drive frame a city where fishing villages, glass office towers, and the largest film industry on earth sit within a few kilometres of each other.
Mumbai has a tropical wet and dry climate governed almost entirely by the southwest monsoon. The year divides into three plain seasons: a hot, humid pre-monsoon summer (March-May, 32-34°C with humidity above 70%), a torrential monsoon (June-September, delivering roughly 2,000-2,300mm - close to 95% of the annual rainfall), and a dry, comfortable winter (November-February, 17-33°C with almost no rain), which is unambiguously the best time to visit. Temperatures never drop far - Mumbai has recorded frost never and rarely falls below 16°C even in January - so the variable that actually shapes a trip is rainfall and humidity, not heat. July is the wettest month by a wide margin, frequently exceeding 800mm, and the sea's moderating influence keeps the daily range narrow year-round.

The seasons
What to expect in each part of the year.
Spring
Months: Mar-May
The pre-monsoon hot season, and the hardest time to be outdoors. Temperatures climb to 33-34°C with humidity rising above 70% through May, and the city feels heavier week by week as it waits for the rain. Skies are clear and hazy, the sea is warm, and Gudi Padwa marks the Marathi new year in March or April.
Summer
Months: Jun-Sep
The southwest monsoon, and the defining season of Mumbai's year. Rainfall exceeds 500mm in June, peaks above 800mm in July, and stays heavy through August and September. Temperatures actually fall to a pleasant 26-30°C, the city turns green, and waterfalls appear in the hills - but flooding, traffic collapse, and train disruption are routine.
Fall
Months: Oct
The short post-monsoon interlude locals call October heat. The rain withdraws, humidity stays high, and daytime highs jump back to 33-34°C with very little breeze - a brief, sticky window between the monsoon and the good weather. Dengue and mosquito activity peaks as standing water lingers. Navratri, Dussehra, and often Diwali land in this stretch.
Winter
Months: Nov-Feb
The dry season and the best time to visit Mumbai without qualification. Days run 30-33°C with cool 17-22°C mornings, humidity drops, rain is essentially absent, and the sea breeze returns. This is peak tourist and wedding season, with the Kala Ghoda Arts Festival in February and the Mumbai Marathon in January. The one drawback is air quality, which deteriorates markedly in this period.
Crowds & peak times
When to expect tourists and when to avoid them.
- High Season
- Nov-Feb (peak tourist and wedding season, highest hotel rates), plus Ganesh Chaturthi and Diwali weeks
- Shoulder Season
- Mar and Oct (dry but hot and humid; moderate rates and manageable crowds)
- Low Season
- Jun-Sep (monsoon; fewest visitors, hotel rates 30-50% below peak, frequent disruption)
