Climate of Tibet

Tibet is a land of climactic extremes and whilst it is not generally as harsh as expected, it is a good idea to be prepared for cold at any time of the year – it is wind chill rather than air temperature that makes the difference here.
In central Tibet weather is usually mild from May through October. Evenings may be cool, particularly early or late in the season. Rain is frequent in July and August.
In Western Tibet and at higher altitudes (Rhongphu, Namtso) it can be cold at any time of year if the wind is blowing off the mountains.
