Bhutan lies in South Asia between Tibet Autonomous Region, China and India. Climate and weather vary according to the altitude, season and place of visit. Bhutan is open all year around for the visitors but it is better to make travel arrangements as per your preference and nature of visit.
Spring (March-May) and Autumn (September-November) are the ideal time to visit Bhutan to get the maximum adventure and trouble free experience. Throughout the spring the weather mostly remains clear and climate is fantastic and serves as the best time for nature lovers to experience the mystifying beauty of nature.
Summer (June-August) in the other could get tricky at times due to the early arrival of monsoon. Usually monsoon is in full swing by early July. Travelers who would strive to get some trekking experience on muddy trail while witnessing swollen rivers, green forests and flourishing paddy filed could choose late summer to plan their adventure.
Winter Season (December to February) is not that crowded in comparison to other seasons. One who prefers the isolation from the hustle-bustle of the peak season might plan your adventure during the winter. During some winter the temperature level goes down (even below freezing point) in Bhutan.
