Climatic characteristics of Hainan Island:

The temperature trend in Hainan is generally affected by latitude, and the temperature decreases with the increase of latitude. In addition, it is also influenced by the topography of Hainan. There are two mountains in Hainan Island, Limu Mountain and Wuzhishan, in the south-central region. In winter and spring, the north wind invaded south, and there were no mountains in the northern part of Hainan. The winter wind drove straight and deep, and there was a quasi-static front weather with continuous rain, which was cold and humid.

However, in the south of Hainan Island, due to the barrier effect of mountains, the influence of winter winds on the southern region has been alleviated to some extent. Therefore, when the northern part of Hainan is deeply troubled by rainy weather, there is not only warm weather in the south, but also precious winter sunshine.

compared with January, the average temperature in July is not so different. In summer, the whole island is generally hot, except for the cool temperature in the central mountainous area, there is little difference in other areas.
