How we pick the best months
- Best: an average temperature of 15–28°C and low rainfall for Kathmandu: under 150 mm, and no more than 60 mm, a quarter above Kathmandu's median month (never set below 60 mm).
- If no month qualifies, we show the three driest months that average 10–30°C instead.
- Wet: 150 mm of rain or more. Rainy: more than 60 mm. Hot: 29°C or more on average. Cool: under 15°C. Cold: under 5°C.
Averages cover day and night, so afternoons are warmer than the figure shown. Weather is only one reason to pick a month: school holidays, festivals and prices matter too.
