Climate of Sanya Hainan Island

MGM Resort Yalong Bay Sanya Hainan Island2Caddie, the owner of www.sunnyhaina.com has been living in Sanya since 1993. Based on her past experiences, there are 3 seasons in Sanya: Hot & Some rains (July-September), Warm & Dry (October till March) and Hot & Humidity (April-June).

It is not too hot from July till September, the highest temperature is around 34 °C. While the temperatures in Beijing, Shanghai, Guangzhou could be over 38 °C. So basically speaking, Sanya is actually cooler than those big cities. With the help of tropical showers or typhoon, day temperature could easily drop down to 26°C-28 °C. Typhoon could be a problem, but usually won’t last more than 3 days. And normally after typhoon, it becomes very hot, and the sun is sharp shining.

Warm & dry season (October to March) is the best time to visit Sanya when it is sunny, dry and warm with average temperature less than 25 d. Sometimes in December and January, the temperature during the day could be less than 25 °C. For people who are used to very warm climate, it is chilly.

Hot & Humidity (April-June) could be difficult for most people as you keep sweating. But it is a good time to get tanned on the beach. The sea breeze helps a lot so you won’t feel that hot if you are on the beach or in a pool.
