Is December a Good Time to Visit Mumbai?
7/10
Good
December is a good time to visit Mumbai (7/10). With 10 daily sunshine hours and only 1 rain days, this month delivers genuinely reliable outdoor conditions, ranking it 8th sunniest of the year in Mumbai. Culture-focused travellers and those who prefer lighter crowds will find December a practical choice, with prices running lower than peak April without sacrificing all the good weather. January offers a similar profile at lower hotel rates if dates are flexible. The main practical note: Mumbai's popular sites are busiest between 10am and 3pm regardless of season. Arriving at opening time or after 4pm makes a significant difference to the experience. Planning tips: accommodation is generally available without long lead times, and flight prices are typically lower than peak season. Flexible travellers will find the best deals by booking 2-4 weeks ahead. Mid-week arrivals consistently unlock lower hotel rates than weekend check-ins.

Temperature in Mumbai in December
The 10°C day-night temperature range is typical for continental climates: a light jacket in the morning that you shed by midday and need again after sunset. At 78% humidity, the 30°C daytime high feels 2-4°C warmer in practice: quick-dry fabrics and shade-seeking between noon and 3pm are the sensible response. The UV index of 3 is low, meaning sun exposure is minimal concern and sunscreen is largely optional. Winds are calm at an average 14 km/h, so wind-chill is not a factor in planning your clothing. In Fahrenheit: 86°F average high, 68°F overnight low. Data sourced from Open-Meteo ERA5 climate reanalysis (1991–2020 normals).

Packing for Mumbai in December means dressing for 30°C days and 20°C evenings. A lightweight linen or cotton shirt with loose-fit trousers or a sundress handles the 30°C daytime heat. Evening temperatures settle at 20°C, a modest 10°C drop that a light cardigan or denim jacket covers. For footwear, breathable walking sandals work for casual exploration, but closed-toe trainers are better for uneven surfaces in the historic centre. For temple and religious site visits, carry a lightweight scarf or sarong to cover shoulders and knees, required at most major sites across the region. At 78% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.
Local tip: Loose-weave linen and moisture-wicking fabrics are the practical choice in Mumbai's heat and humidity. Many shopping centres run air conditioning at near-arctic levels, so a thin layer in your bag prevents discomfort indoors.
Events in Mumbai in December
December has no major festivals or public holidays in Mumbai, which is one of its practical advantages for independent travellers. Attractions run at lower capacity than during peak event periods, queues are shorter, and accommodation is easier to find without needing to book many months in advance. Local restaurants, markets, and transport operate at a relaxed pace, making this an ideal time for visitors who prefer a more authentic, unhurried experience of everyday city life rather than large crowds drawn in by a single major headline event.

Why is Mumbai warm in December?

Climate data: Open-Meteo ERA5 (1991–2020).
