Weather in Kathmandu in April

Prime time. If you get to pick your dates, April is the one. Highs average 28.8 °C, lows 16.1 °C, and rain falls on 7 days — nothing in the month is working against you.

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

Rain on 7 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 28.8 °C days and 16.1 °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: 11 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest April day reached 35.1 °C and the coldest night fell to 11.1 °C, and the wettest single day dropped 53 mm — roughly 147% of the month's rain in one day.

This is the volatile part. April rainfall has ranged from 2 mm to 151 mm across the twenty years measured — a 149 mm spread around an average of 36 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 6.8 km/h, so the temperature on the page is close to the temperature on your skin, and the air is dry at 37% 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

Temperatures hold steady either side: 24.8 °C in March, 28.8 here, 29.8 in May. Nothing about the timing within the month matters much. Rain is the thing that moves: May brings 8 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 0.8 hours across the month. That is between Kathmandu's extremes of 13.9 and 10.4 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 23.1 °C between the year's warmest afternoons and coldest nights. At 1317 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.

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.

April in Kathmandu versus nearby

If Kathmandu is one option among several, the nearby comparison is worth making. Bharatpur is the weaker option in April — 9.3 °C warmer, the same number of rain days. Pokhara is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: April is a compromise. November is 21 points better and is what Kathmandu is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
