The annual average sunshine hours are more than 2000 hours, and the solar radiation can reach11~1.2000 calories. The annual average temperature is 24.4℃, the highest average temperature is about 28℃, and the lowest average temperature is 18℃.

Lishui belongs to the subtropical monsoon climate zone in climate division, which is located near the East China Sea and is greatly influenced by the ocean. It has obvious subtropical maritime monsoon climate characteristics, mountainous terrain and three-dimensional climate characteristics. The superposition of subtropical maritime monsoon climate and hilly three-dimensional climate has created a superior climate environment in Lishui, which is the "hometown of climate health preservation in China" and the first "natural oxygen bar city in China".

5. Guangdong

There is a big difference between the astronomical season time and the natural climate season time in Zhuhai. In a year, the time of each season is different. Even in the same season over the years, the start time is different, and the difference between early and late seasons is more than two months.
