Climate and Weather
Bhutan has four seasons and the climate varies depending on the altitude.
March to May is spring when the weather is pleasant and the flowering trees blossom. June to August is summer, also referred to as the monsoon season because there is plenty of rain. September to November is Autumn and December to February is winter.
Thimphu is located 2,200 meters above sea level and the temperature ranges from 15 to 26 degree Celsius in summer and -4 to 16 degree Celsius in winter.
Central Bhutan usually experiences cooler temperature in the summer and is colder in winter.
The climate in southern Bhutan is hot and humid ranging from 15 to 40 degree Celsius throughout the year.
Rain varies in different parts of the country and in different seasons and years. Similarly, while central Bhutan usually enjoys snowfall every year, in the western region it is unpredictable.
Virtually the entire country is mountaineous, and ranges in elevation from 100m along the indian border to the 7,554m Kulha Gangri peak on the Tibetan border. These two extremes frame a landscape which stretches from sub-tropical to arctic like conditions. The maximum East-West stretch of the country is approximately 300 km and north-South about 150 km.
