Weather in Delhi in April

The month to avoid. Of the twelve, April is the one to avoid. Daytime highs average 39.1 °C and the afternoon is not negotiable — outdoor plans move to early morning or evening.

April ranks 9 of 12 in Delhi: past the worst of the year but short of December, which is the month to book if the dates are open.

Rain falls on only 3 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: 27 days of the month clear 35 °C — that is not a heatwave, it is the month; the day swings 17.2 °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 14 °C, and the wettest single day dropped 29 mm — roughly 193% of the month's rain in one day.

This is the volatile part. April rainfall has ranged from 0 mm to 76 mm across the twenty years measured — a 76 mm spread around an average of 15 mm. The average is real but almost no individual April looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 8 km/h, so the temperature on the page is close to the temperature on your skin, and the air is dry at 24% humidity, which makes the heat far more bearable than the same figure somewhere humid — and dehydrates you faster than you expect.

How April sits in the year

The month is on the way up: 6.3 °C warmer than March, and May adds another 3.5 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in April

12.8 hours of daylight, gaining 0.8 hours across the month. That is between Delhi's extremes of 14 and 10.3 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 35.8 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. Within April itself the daily swing is 17.2 °C, so mornings and afternoons need different clothes.

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 Delhi versus nearby

If Delhi is one option among several, the nearby comparison is worth making. Agra is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Rishīkesh is a better bet in April — 2.3 °C cooler, 1 day more rain.

So: April is a compromise. December is 68 points better and is what Delhi is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
