Bhutan: When to Go

The ideal time for trekking late-September to late-November when skies are generally clear and the high mountain peaks rise to a vivid blue sky. March-May is recognised as the second-best time to visit Bhutan for touring and trekking. Though there are more clouds and rain, the magnificent wildflowers are in bloom and birdlife is abundant. You're likely to get wet no matter what the season, but avoid the monsoon, June-August, when an average of 0.5m (1.5ft) of rain buckets down in Thimphu and up to 1m (3ft) saturates the eastern hills.

Winter is a good time for touring in western Bhutan, bird watching in the subtropical jungles in the south, and white water rafting. The days are sunny and cool but it's quite cold once the sun sets. From December to February the road from Thimphu to Bumthang and the east may be closed because of snow for several days at a time. It would be best not to plan to visit these regions at this time.

In recent years overcrowding has become an issue during the major tsechus (Buddhist festivals) at Thimphu and Paro, which coincide with the best seasons. You stand a much better chance of getting flights, accommodation and probably a more intimate and rewarding festival experience if you schedule your trip around one of the other cultural events.

Weather

Higher parts of Bhutan have pleasant months either side of the rainy season, which lasts from May to September. Days from March to April and October to November are generally warm with less rain, decent sunshine and temperatures between 25-30°C (77-86°F). Nights can get a bit fresh between November and March. Lower parts of the country experience heavier falls and warmer temperatures during the day across this time.
