Weather in Mumbai in April
India · 20-year averages, April
The month to avoid. Of the twelve, April is the one to avoid. Daytime highs average 40 °C and the afternoon is not negotiable — outdoor plans move to early morning or evening.
April ranks 11 of 12 — near the bottom of Mumbai's year. December is the month that works, and the swing between the two is 47 points, which is a different holiday rather than a slightly better one.
Rain falls on only 1 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for heat management rather than style: shade, water, and a schedule that gives up on the middle of the day.
What the averages hide
Averages flatten a month, and this one hides a few things: 30 days of the month clear 35 °C — that is not a heatwave, it is the month; the day swings 15.3 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest April day reached 45.5 °C and the coldest night fell to 20.5 °C.
April is dependably dry, and that reliability is the point: across the twenty years measured, the wettest April on record still only managed 14 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 Aprils brought 7 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.
Wind is light at 8.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 52%.
How April sits in the year
This is a turning point in the year — March and May sit on opposite sides of it, so the month contains the change rather than following it.
Daylight in April
12.6 hours of daylight, gaining 0.5 hours across the month. That is between Mumbai's extremes of 13.3 and 11 hours, so days are long enough not to constrain the plan.
Sea temperature
The sea sits at about 28.6 °C in April — 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.
April in Mumbai versus nearby
If Mumbai is one option among several, the nearby comparison is worth making. Virār is a better bet in April — 10.3 °C cooler, 1 day less rain. Pune is close enough to be a coin toss — within a degree on temperature, the same number of rain days.
So: April is a compromise. December is 47 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.
