Weather in Mumbai in July

A hard month. July asks something of you. Go in knowing what. You should expect rain on 29 days of the month, which is more days wet than dry.

July ranks 7 of 12 in Mumbai: past the worst of the year but short of December, which is the month to book if the dates are open.

Rain on 29 of the month's 31 days, 19 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Natural fibres and a second shirt for the day. At 90% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 7 days top 30 °C — hot spells arrive, but they break; the day barely swings — 3.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 34.7 °C and the coldest night fell to 24.4 °C, and the wettest single day dropped 211 mm — roughly 25% of the month's rain in one day.

July is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest July on record still delivered 1298 mm against 127 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 834 mm average is a reasonable planning figure, not a promise.

Wind is light at 14.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 90% is the real story though — it is the number that decides how the day feels, not the 29.3 °C.

How July sits in the year

Temperatures hold steady either side: 32.6 °C in June, 29.3 here, 28.8 in August. Nothing about the timing within the month matters much. Rain has already shifted: 6 days more than June had.

Daylight in July

July is at or near the longest days of Mumbai's year: 13.2 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 28.3 °C in July — warm enough that the water offers no relief from the heat. 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

Shoulder. The value months — prices ease off and you get the place closer to itself.

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

July in Mumbai versus nearby

If Mumbai is one option among several, the nearby comparison is worth making. Virār is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Pune is a better bet in July — within a degree on temperature, the same number of rain days.

So: July is a compromise. December is 31 points better and is what Mumbai is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
