Of four different seasons Bhutan experiences in a year, spring and autumn are considered the most favorable for tourists. That is why the two seasons always witness a higher number of tourist arrivals compared to that of in winter and summer.
The beauty of spring season is manifested in the blossom of so many flowers, especially rhododendrons. This is the time when Bhutan’s flora is at its best.
Another specialty of the season is the clear skies which enables people to enjoy the rising and snow-covered mountains of the Himalayas. Most tourists who visit Bhutan during the spring say there couldn’t be better time to see the country. But the weather, even during the best seasons, sometimes turns out unpredictable.
Tourists intending to visit the country in spring should be equipped with winter clothes should the weather get harsh.
The spring season in Bhutan 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.
Bhutan’s climatic conditions are different at varying altitudes and locations. This is because of the country’s geography being mixed with mountains, plains, and hills. Some places in Bhutan are situated at as low as about 300 meters, while a few others are as high as 7,000 meters above sea level.
Generally, winter in the country is dry and fierce with most places at higher altitudes remaining snow-covered. Summer is humid and rainy, seeing frequent landslides and road blocks. Thus, the time is not advisable for foreigners to visit Bhutan.
The country has three different climatic zones. These are the subtropical in the south, the temperate zone in the central region, and the alpine regions in the north.
