Best Time to Visit Bhutan
In Bhutan you will mostly experience cold European-like weather due to its altitude. Winter lasts here from November to March where temperatures dip below 0° and there is usually snow on the ground.
The rainy season occurs between June and August when the temperature is the warmest but there is a higher chance of rain and can be lower visibility. October and November are arguably the best months, when there is little chance of rain and the skies are clear. The spring months of March, April and May are best for the flora, and the weather is pleasant but not too hot. The valleys with the higher altitudes will have cooler temperatures throughout the year.
