Tibet Climate and Weather Information
Defined as the "Third Pole of the world", Tibet boasts a unique climatic condition due to its exceptionally high altitude. Taking its capital city - Lhasa as an example, the daytime temperature will reach 28 degree Celsius in summer; while in winter it may drop down to -16 degree Celsius. The thinness of highland air makes solar UV radiation in the region a lot stronger than any parts of the world. Besides, the scarce air has less capacity to absorb and retain the heat in the daytime so that the temperature plummets considerably at night. The fluctuation of one day temperature can amount to 15-20 degree Celsius.
The period April - October is regarded as the best tourist season. Please try not to come in winter from December to February as it is freezingly cold and windy on the plateau.
