Bhutan Weather, climate and geography
Weather & climate
Best time to visit:
The climate varies with altitude, with the highest temperatures and rainfall occurring in the south which bears the brunt of the monsoon between June and September.
Temperatures drop dramatically with increases in altitude though days are usually very pleasant with clear skies and sunshine. Nights are cold and require heavy woollen clothing, particularly in winter. Generally, October, November and April to mid June are the best times to visit - rainfall is at a minimum and temperatures are conducive to active days of sightseeing. The foothills are also very pleasant during the winter.
Lightweight cottons in the foothills, also linens and waterproof gear, light sweaters and jackets for the evenings. Upland areas: thick, warm clothing for evenings, particularly during the winter months.
