Modelled 10-year averages (ERA5 / ERA5-Land via Open-Meteo), checked against the Pyramid research station in the Khumbu, 2016-2025 (within about 1–2 °C of the station's measurements). Temperatures only: the model's rainfall is too coarse to trust in rain-shadow valleys such as Manang, so we leave it out. Mountain valleys and ridges vary more than these grid-model averages show.

How to read these numbers

The tables show 10-year averages from a weather model, adjusted for each village’s elevation. They’re good for comparing months and places, but a single day can be much colder, especially at night and in the wind. Each 1,000 m you climb is roughly 6 °C colder.

The seasons

Spring (March to May): warming days, rhododendrons in bloom lower down, haze building towards May.
Monsoon (June to September): most of the year’s rain, cloud hiding the peaks, and frequent Lukla flight delays.
Autumn (late September to November): the clearest skies and the busiest trails.
Winter (December to February): dry and clear, quiet trails, and well below freezing at night up high.
