Bhutan is a year-round destination. With the right information, planning and preparation, you can visit Bhutan at any time of the year. There are many things to do and see, no matter what time of the year it is. Bhutan has four seasons as follows:
Spring (March, April and May)
Spring in Bhutan is beautiful and warm. The valleys come alive with fresh plants and trees. This is the time for blooming rhododendrons, wild azaleas, and edelweiss to cover the meadows like carpet. With clear skies, you will enjoy the views of majestic Himalayas. It is a great time for hiking and trekking. The famous Paro Tsechu and Punakha Domche also take place at this time. Other festivals include Chhorten Kora, Talo Tshechu, Gasa Tshechu, Domkhar Tshechu, and Rhododendron Festival.
Summer (June, July and August)
Bhutan receives most of the rain during summer. It is a wonderful time to visit with so many places filled with flourishing paddy fields and lush green vegetation against a backdrop of the clear blue sky after the rain. This is also the season of popular festivals such as Nimalung Tshechu, Kurjey Tshechu, Haa Summer Festival and Matsutake Mushroom Festival. However, trekking is not recommended at this time of the year as the trails can be muddy and slippery.
Autumn (September, October and November)
This is the ideal time for trekking and travelling. With pleasant and clear skies, you can expect the perfect views of the mountains. This is also the time when the farmlands glow in golden yellow with ripening of paddies, so it is also the best time for photography. Two major festivals, Thimphu Tsechu and Jambay Lhakhang Drup Festival, fall during this period. Other festivals and events are Wangdue Tsechu, Tour of The Dragon (Bicycle Race), Gangtey Tshechu, Tamshing Phala Chhoepa, Jakar Tshechu, Black Necked Crane Festival, Mongar Tshechu, Prakhar Duchhoed, Trashigang Tshechu, and Prakhar Tshechu.
Winter (December, January and February)
Winter months are dry and chilly with clear skies. During this time, much of the treks remain snowbound and impassable especially in the high mountains. But you can still do bird watching and trekking along the valleys in the lower altitudes where temperature is considerably warm and cozy. It is also the best time to visit Bumdeling in the eastern Bhutan and Phojikha in the western Bhutan where the endangered black-necked cranes migrate from Tibetan plateau during the winter.
