In fact, the Tibetan climate is not as harsh as many people imagine it to be. It is suitable for travel to Tibet from April to the beginning of November, and the best time is August and September. But if you only stay in Lhasa, you can go there anytime of the year.Compared with most parts of China, air in Tibet is thin. Per cubic meter air only has 150-170g oxygen, just occupies 62% or 65.4 of that in the lower altitudes; oxygen content is about 70% (in one cubic meter air), while summer is about 80%.
The climate in highland Tibet belongs to the typical downy special climate. Climates are much different in different areas in Tibet and temperatures vary greatly within a single day. Climate in southeastern Tibet (e.g. Nyingchi) is gentle and temperate with the average temperature of eight degrees; In western Tibet (e.g. Nakqu), the average temperature is below zero degree; While in Lhasa and the central part of Tibet, the climate is normal and nice for traveling. Visitors would not feel cold in winter nor hot in summer, especially from March to October, the best seasons for traveling. Most annual rainfall comes in the rainy season that starts from May to September, when the precipitation covers 90 percent of the whole year. Usually it rains at night in Lhasa, Shigatse and Chamdo area. The precipitations gradually decrease from 5000 millimeters in the lower part of southeast to just 50 in the northwest.
