Climate Chart of Kathmandu, Nepal

Climate overview

Temperature

Monthly mean temperatures are lowest in January, at 10.4 °C, and highest in July, at 22.2 °C. These are averages for each month, not daytime maximum temperatures, so they should not be read as a forecast of afternoon heat or the range between day and night. Across the calendar-month means, the unweighted mean is 17.6 °C; it provides a broad annual reference rather than a day-weighted average.

Rain

Mean daily rainfall is lowest in November at 0.20 mm/day, making that month a conditional option for visitors prioritising lower average rainfall. The highest monthly mean is in July at 26.48 mm/day, a useful prompt to prepare for rain when planning outdoor activities then. These are daily averages, not monthly totals, and they do not show how often rain falls or guarantee dry or wet days. The unweighted mean across monthly daily averages is 8.02 mm/day.

Sunshine

Mean daily sunshine reaches its highest value in April at 10.77 hours/day, and its lowest in July at 6.62 hours/day. These figures can help visitors weigh daylight outdoor planning, but sunshine duration is not the same as day length and does not promise clear skies throughout a visit. The unweighted mean across monthly sunshine averages is 9.06 hours/day hours per day.

Snow

The highest monthly mean daily snowfall is 0.12 mm/day in February; the unweighted mean across monthly daily averages is 0.01 mm/day. These recorded averages describe snowfall amounts, not the number of snowy days, snow depth, snow cover or whether conditions suit skiing.
