Weather and climate of Punakha

July,02 2019 BY Lobsang Tsering 0 COMMENTS

One of the 20 Dzongkhags (districts) of Bhutan, Punakha is one of the most popular tourist destinations in the country, along with Thimphu, Paro, and Bumthang. The former capital of Bhutan until 1955, Punakha lies around 72 kilometers from the modern-day capital of Thimphu, although this trip takes around three hours by car. A lower-altitude district than its peers in tourist popularity, Punakha has a much milder climate throughout the year than Thimphu, Paro, and Bumthang, which makes it a pleasant place to visit even in winter.

Bhutan and Punakha Weather Overview

In general, the weather in Bhutan depends largely on the altitude. The higher you go, the lower the average temperatures and the drier it becomes, even in the rainy monsoon season. In the northern areas of the kingdom, the summers are drier than in the low-altitude south, and winters are much colder, with temperatures getting to well below freezing, especially at night.

Punakha WeatherTable of Punakha Weather Guide

Punakha, in stark contrast to the rest of northwest Bhutan, is relatively mild, mostly because the Dzongkhag lies in a valley that is much lower in altitude than its comparable Dzongkhags in the region. Winters are generally milder, and summers are warmer, though it does mean that the district gets more rainfall than other districts on the same line of latitude. Monsoon rains in Punakha can be heavier than in the neighboring Thimphu, which makes it more ideal for visits from autumn to spring.
