Bhutan has four distinct seasons, each with its unique climate that varies depending on the altitude.
During the months of March to May, the country experiences spring, characterized by pleasant weather and the blossoming of flowering trees. Summer, which lasts from June to August, is referred to as the monsoon season because of the mild and humid rainy weather conditions. Autumn takes place from September to November, while winter spans from December to February.
Thimphu, located in Western Bhutan at an altitude of 2,200 meters above sea level, experiences a temperature range of 15 to 26 degrees Celsius during summer and -4 to 16 degrees Celsius during winter. On the other hand, Central Bhutan has cooler summer temperatures and colder winters.
Southern Bhutan, which has a hot and humid climate, experiences temperatures ranging from 15 to 40 degrees 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.
