Warm & dry season (October to March): Best time to visit Sanya in terms of climate conditions

October till March is the best time to visit Sanya Hainan in terms of weather conditions when it is sunny, dry and warm with an average temperature less than 25 °C. Sometimes in December and January, the temperature during the day could be less than 25 °C. For local people who are used to a tropical warm climate,  we will say: it is cold today, we need a jacket.

Raining Season (July till September): Cooler than most places on Mainland China

It is not too hot from July till September, the highest temperature is around 34 °C. While at the same period, the temperatures in Beijing, Shanghai, Nanjing, Wuhan and other big cities on Mainland China could be over 38 °C. So basically speaking, Sanya is actually cooler than those big cities. With the help of tropical showers or typhoons, temperature could easily drop down to 26°C-28 °C. The typhoon could be a problem but usually won’t last more than 3 days. Normally after a typhoon, it is still cool with some tropical showers.

Hot & Humidity (April-June): Strong Sunshine, almost no rain, best prices on flights and hotels

It could be very hot and sunny and you might 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. As it is low season in Sanya from April till June, most hotels and airlines offer a great discount. So if you like strong Sun, April till June is the best time for the best prices for a year.
