Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in KR as well as at Kathmandu, which is why this table differs from the same one read from another country. A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. Crowds alone never make a month “avoid”: that is reserved for weather worth skipping.
The year in Kathmandu
Kathmandu experiences a distinctive dry season in winter (December to February) and a severe monsoon from June to September. Visitors should plan accordingly, as heavy rainfall can disrupt travel plans.
| Busiest |
early May to mid Jun — This period marks the spring season where temperatures are warm and rain is beginning, attracting many tourists.
early Oct to mid Nov — The autumn season brings clear skies and moderate temperatures, making it ideal for trekking and outdoor activities.
|
|---|---|
| Quieter, still good |
mid Feb to late Apr — These months provide mild weather and lesser crowds compared to peak season.
mid Nov to late Dec — Post-peak season offers good weather with few tourists and lower prices.
|
| Wet or stormy |
mid Jun to late Sep — monsoon, severe
|
| Watch out for | haze; wildfire season in dry months |
This section was written by a language model from the climate figures above, and nobody has checked it. The month-by-month table is measured — ten years of ERA5 readings and published holiday calendars — and where the two disagree, the table is the one to believe. The busiest and quieter periods here also count toward the crowd score, which is 20% of the ranking.
