Bhutan is a year round travel destination.
Spring and Autumn are generally regarded as the best time to visit Bhutan for their favourable temperature and weather conditions. Also, spring is the time to experience the stunning blossoming of a wide range of flora in Bhutan, while Autumn is the perfect time to witness the ripening of rice crops and harvesting. Both seasons also have the highest concentration of local festivals called the Tshechus
*Spring and Autumn: March, April, May, September, October, and November are considered the high and peak season to travel to Bhutan.
Summer is a time of evergreen in Bhutan with light showers typically in the late afternoon, while Winter is a time to photograph the crisp blue sky with the beautiful snow-capped mountains. Bhutan experiences mild winter, with snowfall reaching the populated areas only once to thrice throughout the year. Summer and winter are also the time with the least footfall in Bhutan where it has the least crowd in Bhutan giving you a sense of exclusivity.
*Summer and Winter: January, February, June, July, August, and December are considered the low and non-peak season to travel to Bhutan.
