Climate Data Historical

Bhutan can also be characterized into six agro-climatic regions: alpine, cool temperate, warm temperate, dry sub-tropical, humid sub-tropical, and wet-sub tropical. Climate varies dramatically because of the countries varied topography and geographical location at the edge of the tropical circulation in then north and Asian monsoon circulation in the south. The northern part of the country is characterized by snowcapped peaks of elevations above 7,300 meters with abundant glaciers and alpine pastures. Regions at lower elevations and closer to the south tend to have higher temperatures as well as more precipitation while the northern regions of the country are often cooler and experiences less precipitation.


  • Bhutan experiences northern summers between June and August with historical average temperatures reaching 17.8°C in July.
  • Historical average temperatures are increasing primarily in southern regions of the country that tend to have lower elevations. 
  • Historical observations find that the mean of daily low temperature is increasing at a steeper pace than the mean of daily high temperature (Berkeley).
  • The southern belt of the country at the foothills of the Himalayas has a subtropical climate. The central belt is characterized experiences cool winters, hot summers between June and September, and moderate rainfall. The Northern belt consists primarily of snowcapped peaks and alpine meadows that experience cold winters and cool summers (Gov. of Bhutan, 2016).


  • Precipitation ranges between seasons and regions. Historical average seasonal precipitation ranges from 3.85mm in the driest winter month and 452.18mm.  
  • Bhutan experiences a pronounced monsoon season with precipitation peaking in July.
  • Historical trends show significant spatial and seasonal variability. Precipitation is highest near the northern and southern borders of the country.
