Weather in Guwahati in April

A hard month. April is a hard month in Guwahati, and worth planning around. You should expect rain on 20 days of the month, which is more days wet than dry.

April ranks 7 of 12 in Guwahati: past the worst of the year but short of January, which is the month to book if the dates are open.

Rain on 20 of the month's 30 days, 8 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 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: 10 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest April day reached 40.4 °C and the coldest night fell to 15.8 °C, and the wettest single day dropped 61 mm — roughly 27% of the month's rain in one day.

April is moderately variable: 34 mm in the driest year against 528 mm in the wettest, around an average of 230 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 2.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 68%.

How April sits in the year

Temperatures hold steady either side: 31.9 °C in March, 34 here, 34.7 in May. Nothing about the timing within the month matters much. Rain is the thing that moves: May brings 5 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in April

12.8 hours of daylight, gaining 0.7 hours across the month. That is between Guwahati's extremes of 13.8 and 10.5 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 23.4 °C between the year's warmest afternoons and coldest nights.

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 Guwahati versus nearby

If Guwahati is one option among several, the nearby comparison is worth making. Dārjiling is a better bet in April — 12 °C cooler, 7 days less rain. Kolkata is close enough to be a coin toss — 4.9 °C warmer, 11 days less rain.

So: April is a compromise. January is 64 points better and is what Guwahati is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
