Thanks to the moderate climate, Bhutan happens to be an all-year round destination which never faces the extremities of the weather such as a heatwave, floods, or heavy snowfall. As a result, a lot of tourists spread themselves out in between the spring (March and April) and the autumn season (October- November).
Therefore, the blossoming of flowers, change in winds, and slight fluctuation of temperature can be taken as an indicator of where and how traveling are visiting Bhutan.
