The climate characteristics of Guizhou Plateau can be simply summarized as follows: abundant rainfall, moderate rainfall, more rainy days, cloudy all year round, less sunshine, humid climate, mild temperature year by year, slow winter and cool summer.

Guizhou Plateau is foggy, cloudy and rainy, so there is much less sunshine. The annual sunshine hours in Guizhou Plateau are generally around 1.200- 1.400 hours, which is only about half of that in the Loess Plateau, and the average daily sunshine time is only 4 hours. Judging from the sunshine hours in the whole year, Guizhou Plateau is one of the areas with the least sunshine in China, which is a disadvantage of its climate.
