Monsoon brings heavy downpours and occurs between June and August when the temperature is normally between 8° and 21°C (46°-70°F).
Winters in Bhutan are cold and dry with most high lying places snow-covered. Winter lasts here from November to March.
And summers are humid and the country experiences heavy rains and frequent road blocks.
However, Bhutan’s climatic conditions are different at different places and locations. It is because the country’s geography consists of mountains, plains, valleys, and hills. Some places in Bhutan are as low as 100m, while others are more than 7,000m above sea level. In the north of Bhutan on the borders with Tibet it is perennially covered with snow.
Bhutan has three different climatic zones: subtropical in the south, temperate in the central region, and alpine in the north.
Climate
Bhutan experiences four distinct seasons, similar in their divisions to those of Western Europe: spring, monsoon, autumn, and winter. Most tourist visit Bhutan in spring and autumn.
Spring is the time when Bhutan’s rich flora is at its best as hundreds of varieties of flowers blossom. And during this time around, the skies are clear and you can see towering snow-covered mountains of the Himalayas.
Even in spring Bhutan’s fierce winter, especially in high altitudes, isn’t over. Tourists who intend to visit during this time are advised to bring along some winter clothes. Spring season starts from March and ends roughly in June.
Another good time of the year – autumn – begins from September and lasts till the end of November.
