Spring (March – May)

Warm days, blooming rhododendron and jacaranda, and the huge Paro Tshechu. This is peak season, so book flights and hotels early.

Summer (June – August)

The monsoon brings afternoon rain and cloud that can hide the mountains, but the valleys are lush and green, prices drop, and the crowds disappear. Good for culture-focused trips, less so for trekking.

Autumn (September – November)

The clearest skies of the year, ideal trekking conditions, and back-to-back festivals including Thimphu Tshechu. The other peak season.

Winter (December – February)

Cold in the high valleys but bright and quiet. Punakha and the lower south stay mild, and this is the season to see black-necked cranes in Phobjikha.
