I plan to go to Xining, Qinghai in September 14, and I will probably spend 10 days like this. I wonder what the weather is like there now, and what is the weather like in Dunhuang? What should I bring? I'm from Xining, Qinghai .. 9. 14. It's been another week, and the forecast hasn't come out yet. I checked the weather forecast, and it's only 4-7 days, mostly rain or something. I don't watch the weather forecast, so I'll tell you the weather these days ... It's been raining continuously in August, especially since mid-August, and it's basically heavy or small rain, but it's always cloudy anyway. But judging from the weather forecast and the intensity of the sun, it should still rain ... Now that the temperature here is getting cold, you should be a travel enthusiast. When you come, you should bring a coat, and you definitely don't need short sleeves ... If you want to go to Qinghai Lake, it's quite cold there now, like going to Qinghai Lake in the morning, you should bring at least a thin sweater in your coat, and now the plateau is very cold, especially at high altitude in the morning, which is obviously cold and windy. Besides, we don't think about ultraviolet rays now, it's all over! ! ! Dunhuang, in Gansu, I don't know, but you can go from Golmud, Qinghai. Probably, the terrain is very similar to Golmud. It's all Gobi desert, and the climate is characterized by strong wind. It's no problem to put on the coat I mentioned above ... I can only answer these ... I'm really tired after playing so much! ! ! I hope to adopt extra points! ! !
