It is hard to generalize about Bhutan's weather since the mountain climate varies enormously from region to another. It varies with the altitude and can also reach extremes of heat and cold within the 24 hours at any given altitude. Southern Bhutan is tropical, with monsoon season. The East is warmer than the West. The central valleys of Punakha, Wangdi Phodrang, Mongar, Trashigang and Lhuntshi enjoy a semi tropical climate with very cool winters, whereas Haa, Paro, Thimphu, Trongsa, Bumthang and Phobjikha have a much harsher climate, including occasional snowfalls in winter. The north of the country is inhabited up to 5,00 meters (16,400 feet) in summer. The climate there is rough, with monsoon rains in summer and heavy snowfalls in winter that block the passes leading into the central valleys.

The wide range of temperatures does not make dressing easy. The best solution is to wear several layers, such as a cotton shirt, pullover, wool cardigan and jacket, which can be taken off or added as needed. Do not bring delicate clothes: conservative sportswear is the appropriate style for a traveler in Bhutan.
