Bhutan is a year-round destination with four seasons: spring (March to May), summer (June to August), autumn (September to November) and winter (December to February). Spring brings nature in full bloom and is a favourite for trekking. Autumn offers bright, sunny days and the biggest festivals. Winter is crisp and clear with snow above 3,000 metres, and summer brings the monsoon, mostly affecting the south. Because of the range of altitudes, the climate varies a lot by region.
