Basically, the Tibetan climate is not as harsh as many people imagine it to be. The best time of year to be in Tibet is from April to the beginning of November, after which temperatures start to plummet.

The central Tibet, including Lhasa, Gyantse, Shigatse and Tsedang, generally has very mild weather from April to November, though July and August can be rainy - these two months usually see around half of Tibet's annual rainfall.

October and November often bring some dazzling clear weather and daytime temperatures can be quite comfortable at Tibet's lower altitude.

The coldest months are from December to February. It is not impossible to visit Tibet in winter. The low altitude valleys of Tibet (around Lhasa, Shigatse and Tsedang) see very little snow.

Spring does not really get under way until April, though March can have warm sunny days and is not necessarily a bad month to be in Tibet. More specific information in different areas:
