When should we go to Tibet?

July to September every year is called the "golden season" in Tibet, which is the peak season for tourism. Tourists, mountaineers and scientists from home and abroad flocked to Tibet. Although it's a long way, the world is getting smaller now. The road to Tibet is in the air, on the ground and in the west. The annual average temperature 18-20 degrees Celsius, and the daily average temperature changes greatly, which is really "wearing cotton-padded jacket at night and yarn at noon". In places above 5000 meters above sea level in Ali, in August, the daytime temperature is above 10 degrees Celsius, and the nighttime temperature drops below zero degrees Celsius. Precipitation: The annual precipitation is very small and seasonal. From October of 65438/kloc-0 to April of the following year, the precipitation only accounts for 0% to 20% of the annual 10; The rainfall from May to September is very concentrated, generally accounting for about 90% of the annual precipitation. Special note: May-July and September 9- 10/0 can be visited every year to avoid the danger of heavy snow and landslides. Offering Hada is the most common etiquette for Tibetans. Hada is usually given at weddings, funerals, folk festivals, visiting elders, worshipping Buddha and welcoming guests.
