Since Tibet is a unique and hot tourist destination among travellers globally, what's the best travel time to Tibet is frequently asked by tourists. Generally, the best travel time to Tibet is from April to October taking Tibet climate into consideration. In fact, the best time to Tibet is different for different travellers. You will find out your best time to travel to Tibet here.
When you make a Tibet tour, you will find that Tibet enjoys many sunny days.
Tibet is in a high plateau, and it belongs to typical downy special climate. Climates are quite different in different areas of Tibet. The eastern Tibet which is at a lower elevation is warmer than western Tibet. In some mountain areas, you can experience four seasons in the same area. The weather in a day varies greatly, too. The night is cold while the day is warm. It spans 12-15 degrees centigrade in a single day.
Climate in southeastern Tibet including Nyingchi and Chamdo is balmy with an average temperature of eight degrees centigrade; while in western Tibet (Shigatse and Nagqu) is quite cold with an average temperature below zero degree.
However in the central area of Tibet, the climate of Lhasa and Tsedang is more favorable for traveling. Travelers can visit these two areas all year around, not too hot in summer and not too cold in winter.
Grand Potala Palace, a must-see site for Lhasa tours, can be visited all year around.
According to our more than 10 years' experience of organizing Tibet tours for foreigners, we think that from early April to late November is the pleasant time to visit all areas of Tibet, not cold. The late November to next March is ok for paying a visit to Lhasa, Nyingchi or some cities having good accommodation with heating or heater, because it is too cold at night. For most visitors, the best time to travel Tibet is between April and October. The best months are May, June, September and October as July and August are rainy months.
Generally speaking, early April is the beginning of travel season, which lasts to mid-June when a large number of Chinese travelers rush to Tibet for summer holiday. Late June to the end of National Holiday is the peak travel season when some important festivals held in Tibet, like Shoton Festival, Gyantse Dawa Festival and Nagqu horse riding Festival. After mid October, Tibet turns to winter and as the visitors reduce greatly, more than half of hotels are closed for the poor reservation.
As for the best time to travel to Tibet, we have different ideas from other travel companies or travel guide books. The best travel time depends on your travel requirement.
1. If you want an extremely cheap price, go to Tibet in winter, from December to next March. All the things are quite cheap; even the tourist sites offer 30-50% discount on entrance fee. Hotels are cheap, too. You can enjoy 5 star hotels with less than 100USD including breakfast. Compared with traveling in August, the cost of a winter tour is only 50%-60% of a summer tour. Because of the poor amount of visitors, the Potala Palace allows you to spend even a whole day in it. Besides, the monks are not busy and have spare time to chat with you.
2. If you like trekking, do it at May or September when the monsoon will never bother you and the weather is balmy and pleasant.
3. If you love Mt. Everest and want to see the clear face of it, try to avoid the rainfall season and foggy weather. The best time to visit Mt. Everest is April, May, September and October.

4. If you love to visit the grass land in north Tibet, do the tour in July when the flowers bloom in vast grassland and groups of yak and sheep, Tibetan nomad tents spread all over the grassland.
5. Those who want to drive to Tibet through Sichuan-Tibet highway should avoid the rainy season. There will be mudslides, cave-ins and mire on certain sections of the road, blocking the passage of vehicles.
