Temperatures of Bhutan

The temperatures in Bhutan vary significantly depending on the season, altitude, and region. Bhutan’s geography ranges from subtropical plains in the south to subalpine Himalayan peaks in the north, which greatly influences the climate and temperatures throughout the year. Here’s an overview of Bhutan’s temperature patterns:

Seasonal Overview

1. Spring (March to May):
