Best Time to Visit Tibet
Despite the high altitude of the Tibetan Plateau, the daytime temperatures are actually quite mild. Between April and November the average temperature ranges form 15-25 degrees Celsius and the skies are generally clear and blue. From July to August though there can be the odd shower during the day. The nights, however, can be very cold and temperatures can drop below 0 degrees Celsius. During the day a light shirt or jumper and lightweight pants will be suitable, but a warm fleece or down jacket is recommended for the evenings.

The best time of year for overland tours in Tibet is from April to November and for treks and Mt. Kailash tour from April to the beginning of October.
