Which city in Hainan Province is the coolest in summer?

There is no data, but I have lived in Hainan for several years.

In terms of temperature, Sanya is higher than Qionghai and Haikou.

Haikou is the northernmost city in Hainan Province, Sanya is the southernmost city in Hainan Province, and Qionghai is in the middle.

The climate of Haikou is like that of Guangdong. It often rains and the weather is wet. It's sultry in summer and cold in winter ~

It seldom rains in Sanya, and the sky is clear in Wan Li. Although it is hot in summer, it is not stuffy and the air humidity is not high. Because of the sea, the sea breeze brings a lot of salt. The climate in winter is pleasant, neither cold nor hot, and the lowest temperature is only about 18 degrees. It is enough to wear a T-shirt during the day and a thin coat at night ~

Generally speaking, the average temperature in Sanya is 5 degrees higher than that in Haikou ~

Although they are all Hainan Island, the climate is completely different ~

Haikou has a subtropical climate, and it often rains. Sanya has a tropical climate and seldom rains. Even if it rains, it will be a storm, and then Wan Li will be clear ~

Sanya is the only tropical city in China ~
