Weather in Mumbai in June

A hard month. June asks something of you. Go in knowing what. You should expect rain on 23 days of the month, which is more days wet than dry.

June ranks 9 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 23 of the month's 30 days, 13 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. Pack for 32.6 °C days and 26.9 °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: 6 days clear 35 °C, so a serious heatwave is normal rather than notable; the day barely swings — 5.6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 40.1 °C and the coldest night fell to 24.3 °C, and the wettest single day dropped 229 mm — roughly 43% of the month's rain in one day.

June is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest June on record still delivered 932 mm against 76 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 535 mm average is a reasonable planning figure, not a promise.

Wind is light at 13.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 80%, high enough to notice on the warm days without dominating them.

How June sits in the year

The month is on the way down: 5.9 °C cooler than May, with July dropping another 3.3 °C. The first week and the last are not the same trip. Rain is the thing that moves: July brings 6 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in June

June is at or near the longest days of Mumbai's year: 13.3 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 29.6 °C in June — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

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

June in Mumbai versus nearby

If Mumbai is one option among several, the nearby comparison is worth making. Virār is a better bet in June — 2.8 °C cooler, 1 day more rain. Pune is a better bet in June — 2.1 °C cooler, the same number of rain days.

So: June is a compromise. December is 37 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.
