Mumbai Weather Month by Month – Temperature and Rainfall

Mumbai stays warm through the year, with humidity strongly affecting how comfortable outdoor sightseeing feels. The main seasonal change is rainfall rather than a dramatic winter-to-summer temperature difference.

How to interpret the figures

The monthly temperatures below describe average daily minimums and maximums, not the full range of possible weather. Rainfall totals are historical monthly averages; a few intense downpours can account for a large part of a month’s rain.

• Coastal breezes do not remove the need for sun protection.
• A lower monsoon daytime temperature can still feel humid.
• Use current forecasts for daily plans and warnings for disruption decisions.

January and February are convenient for walking tours, seafront outings and longer sightseeing days. Mornings are relatively mild, but afternoons usually remain warm.

• January: Average minimum about 17°C, maximum about 31°C; rainfall is negligible.
• February: Average minimum about 18°C, maximum about 31°C; rainfall is negligible.

Plan for warm afternoons

Visit heritage districts earlier, keep water with you and use a café or museum break around midday. A light layer may be useful for an early start or strongly air-conditioned transport, but heavy winter clothing is rarely practical for ordinary city sightseeing.

March to May becomes increasingly uncomfortable for prolonged outdoor activity, especially as nights grow warmer. Coastal humidity can make a moderate-looking temperature feel tiring.

• March: Average minimum about 21°C and maximum 33°C; little rain.
• April: About 24°C to 33°C; little rain.
• May: About 27°C to 34°C; average rainfall around 11 mm.

Schedule markets, walking tours and beach visits for cooler hours. Choose accommodation with effective cooling and keep a substantial midday break. May rain is not a reliable substitute for checking the actual monsoon forecast.

June and July require flexible plans because rain can affect roads, rail services, ferries and outdoor attractions. Monsoon onset varies, and rainfall is not evenly spread across each day.

• June: Average minimum about 27°C, maximum 32°C and rainfall around 493 mm.
• July: About 26°C to 30°C and rainfall around 841 mm.

Keep connections realistic

Stay near the area you intend to explore and leave generous time for airport transfers. Do not enter flooded underpasses or unfamiliar waterlogged streets. Ferry excursions and exposed seafront plans should depend on current operating and weather advice.

August and September remain wet months, although rainfall often varies substantially between spells. A bright morning does not guarantee an uninterrupted afternoon.

• August: Average minimum about 25°C, maximum 30°C and rainfall around 585 mm.
• September: About 25°C to 31°C and rainfall around 341 mm.

Use shorter outdoor windows and keep indoor alternatives nearby. September should not automatically be treated as dry-season travel: check forecasts, ferry operations and road conditions for your exact dates. Carry rain protection even when leaving the hotel in sunshine, and allow extra time before an onward journey.

October and November can feel hotter than visitors expect after the rainiest months. Sunshine increases, humidity can remain noticeable, and occasional rain is still possible.

• October: Average minimum about 24°C, maximum 33°C and rainfall around 89 mm.
• November: About 21°C to 34°C and rainfall around 10 mm.

Resume outdoor plans gradually

These months can suit heritage walks and neighbourhood exploration, but exposed afternoon routes remain tiring. Carry water, take shaded breaks and check the forecast before boat excursions. Festival activity may also affect road access and accommodation demand independently of the weather.

December is generally a convenient month for Mumbai sightseeing, with much less rain than the monsoon period. The historical average minimum is about 19°C, the maximum about 32°C, and monthly rainfall around 2 mm.

Use the longer outdoor windows

Combine a morning heritage walk with a museum visit and an evening promenade. The weather is more comfortable, but sunshine and urban walking can still be tiring.

• Carry a light layer if you feel cold in air-conditioning.
• Continue using sun protection and drinking water regularly.
• Book ahead for Christmas and New Year travel.
• Expect popular waterfront areas to attract substantial evening crowds.

Choose roughly November to February if outdoor sightseeing is your priority and you want a lower chance of rain disrupting the day. Monsoon travel is manageable with flexibility, but it is less suitable for tightly scheduled ferry trips and distant connections.

• Drier months: Pack breathable clothing, walking shoes, a hat and sunscreen.
• Hotter months: Prioritise cooling, water and midday breaks.
• Monsoon: Carry rainwear, quick-drying clothes and waterproof protection for valuables.

Check current IMD warnings, transport updates and local instructions before travelling during heavy rain. Never use historical monthly averages to judge whether a particular day is safe for an exposed activity.
