Weather in Mumbai in January

A good month. January is a solid month to be in Mumbai. Highs average 32.7 °C, lows 17.1 °C, and rain falls on 0 days — nothing in the month is working against you.

January ranks 2 of 12 in Mumbai. Only December scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain is not a factor worth planning around this month. Pack for 32.7 °C days and 17.1 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 5 days clear 35 °C, so a serious heatwave is normal rather than notable; the day swings 15.5 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest January day reached 39 °C and the coldest night fell to 11.1 °C.

January is dependably dry, and that reliability is the point: across the twenty years measured, the wettest January on record still only managed 3 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Januarys brought 2 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.

Wind is light at 7.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 51%.

How January sits in the year

Temperatures hold steady either side: 31.8 °C in December, 32.7 here, 35.5 in February. Nothing about the timing within the month matters much.

Daylight in January

January sits at the dark end of Mumbai's year — 11.1 hours of daylight against 13.3 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 26.2 °C in January — warm enough to stay in as long as you like. The sea peaks at 29.7 °C in May and bottoms out at 26.1 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

January in Mumbai versus nearby

If Mumbai is one option among several, the nearby comparison is worth making. Virār is a better bet in January — 6.8 °C cooler, the same number of rain days. Pune is a better bet in January — 3.4 °C cooler, the same number of rain days.

So: January is effectively as good as it gets here — 3 points behind December, which is inside the margin where the weather stops being the deciding factor and price starts being it.
