October to December is the ideal time to visit Bhutan as the air is clear and fresh with sunny skies. January and February are colder, but from then until April the climate remains dry and pleasant and in late spring the famous rhododendrons bloom spectacularly, flooding the valleys with colour. Heat and humidity increase from May, and from June to September the monsoon rains cover the mountains. If you're interested in seeing the rare black-necked cranes, we recommend visiting the Phobjikha Valley between late October and mid-February.
The Spring months- March, April, May is the favourite time to visit Bhutan. Nature lovers who are keen on local flora should consider visiting Bhutan end of April or in May. Flowers would be in full bloom.
The Summer months – June, July and August - are monsoon season in Bhutan; a time of very heavy rain when, over three months, half a metre of rain falls in Thimpu, up to a metre falls in the eastern hills, and the mountains become obscured by thick cloud.
The Fall months- September, October, November is another high and crowded season for Bhutan. Though Bhutan does not offer browning forest nor Maples, the mild weather in autumn makes it a perfect time to visit Bhutan. Thimphu Festival usually takes places at the end of September or early October.
The Winter- December, January, February is the best time to avoid the crowd and catch the Black-Necked Cranes, winter would be the time to go. To catch Himalayan blue sky without paying the additional tariff, consider visiting Bhutan in December. The temperature will not be too cold yet as lowest temperature usually takes places near the end of January. In January or February, Paro and Thimphu may experience a one-day snow-– well worth it for those who can brave the chill.
About 20 percent of international tourists arrive in the month of October. We would highly recommend travelers to book at least three months in advance if you are considering of traveling in the month of October. Travelers who would like to avoid the crowd but enjoy the best weather may want to consider the month of May and November. If you would like to save as much as possible with the lowest possible price, consider traveling in June or December. You would enjoy the low season price while still having favourable weather.
