Nepal Kathmandu Weather in April — Climate Guide
April in Kathmandu is very-high
April is very-high for Kathmandu.
April is the warm heart of spring and one of the year's top months — afternoons around 28°C, comfortable nights near 12°C, and mostly clear, bright weather. Rainfall ticks up (about 60mm) with the first occasional pre-monsoon afternoon showers and thunderstorms.
This is peak trekking season, so Kathmandu buzzes with trekkers heading to Everest Base Camp and the Annapurnas, and the city's hotels and agencies are at their busiest. Book accommodation well ahead and expect peak prices.

Kathmandu in April — Full Picture
April is the warm heart of spring and one of the year's top months — afternoons around 28°C, comfortable nights near 12°C, and mostly clear, bright weather. Rainfall ticks up (about 60mm) with the first occasional pre-monsoon afternoon showers and thunderstorms.
This is peak trekking season, so Kathmandu buzzes with trekkers heading to Everest Base Camp and the Annapurnas, and the city's hotels and agencies are at their busiest. Book accommodation well ahead and expect peak prices.
A spectacular event is Bisket Jatra, the Nepali New Year festival, centered on Bhaktapur in mid-April — chariot processions, tug-of-war over the towering pole, and crowds filling the old city. It's one of the best times to experience Bhaktapur.
The weather is comfortable for sightseeing, though midday UV is strong (sunscreen and a hat are essential) and afternoon haze or the occasional thunderstorm can reduce mountain visibility later in the day — mornings are clearest for the mountain flight.
What to Wear & What to Pack
Warm pre-monsoon spring at its best. Warm afternoons around 28°C, comfortable nights near 12°C. Light, breathable clothing, sunscreen, sunglasses, a hat. A light layer for the occasional cool evening. Peak trekking season.
