The weather in Yunnan is like spring all year round.

1. Kunming is located in the low latitude area. Due to the low latitude, sufficient heat and little change in temperature in four seasons, the temperature in winter is higher.

Kunming is located in the Yunnan-Guizhou Plateau, with an altitude of1800-2000 m. Because of its high altitude, the temperature is lower than that in the plain area of the same latitude, so the summer temperature will not be too high. The temperature difference between winter and summer is small, so there is a saying that there is no cold and heat in four seasons. There is a saying in Kunming that the seasons are like spring.

2. There is a lot of autumn rain in Kunming, which is mainly influenced by the quasi-static front stop in Kunming.

The mountainous terrain in the northeast of Yunnan-Guizhou Plateau blocked the cold front and weakened it into a quasi-static front. When the cold air is strong and the front is located to the west of Kunming, and the eastern part of Yunnan is below the static front, the temperature drops suddenly, and the weather turns cloudy or there is light rain, which makes autumn cool, so there is a saying that "it becomes autumn when it rains".
