The climate of Bhutan

The geographical position of Bhutan, nestled in the eastern Himalayas between China to the north and India to the south, plays a significant role in its climate and weather conditions. Contrary to the "ET" Köppen climate classification which corresponds to a Tundra Climate, Bhutan experiences a greater diversity in weather patterns due to its complex topography and altitude variations. Mean annual temperatures seldom dip below freezing, but regions with higher altitude can see large temperature ranges within a day. Precipitation, primarily rainfall, is moderate and most pronounced in the summer months with annual totals averaging 350mm. During winter, drier conditions prevail, often with sporadic snowfall in the upper reaches. With days frequently cloudy, the country experiences temperatures from 15°C to 18°C in summers, although the average temperature of the warmest month is less than 10°C.
