What's the weather like going to Yunnan in September?

At the beginning of September, you can bring two long-sleeved shirts and jeans, or you can bring a short sleeve, because it will still be a little hot during the day (currently 26-28 degrees), and bring a slightly thicker coat, just like the coat worn in the early autumn in the north, because the temperature in Shangri-La is a little low.

The rainy season gradually passed, and there was not much rain when it came.

The clothes are very dry, because the climate in Kunming is very dry, and the jeans will dry after hanging outside for a day.

Banna is hotter in September, so you should wear short sleeves. Although the air is a little humid, clothes dry easily because of the heat.
