Sanya Weather

Sanya belongs to the tropical coastal monsoon climate with very warm weather all year around. Its daily average temperature is 25 °C (77 °F) and annual rainfall is 1,279mm (50 inches). The rainy season is from June to October. Every year there are about 300 days of sunshine. Winter is very pleasant with no frost nor snow. Flowers are in full bloom throughout the year. Located on the same latitude as Haiwaii, Sanya is famed for its clear and fresh air, abundant sunshine, and fine beach; it is thus praised as the "oriental Hawaii ". Sunshine is strong throughout the year, so bring sun protection such as sunglasses, hats and sun block. Mosquito repellant is also suggested.

It is the city with the best air quality in China. According to the data of air quality collected by the World Environmental Protection Organization in 158 cities in 48 countries in 1999, the aggregative index for air and environment of Sanya ranked the first place in the country and the second place in the world, only after Havana, the capital of Cuba. It is also nicknamed the "natural oxygen bar".

Sanya is suitable for travel all year round, though the best period is from September to April. China's National Day Holiday (October 1-7) and Chinese New Year (around February) are the peak seasons when lots of people pour to Sanya for vacation; it is suggested to place tour and hotel bookings in advance. Have a look at our Sanya Tours and choose your time of travel.

Hello. We are planing to go to Sanya by end of December. Is the sea still warm for swimming? How is the general weather? I want to get a lot of sun! thanks!
Hi Martin, based on the former data, the temperature in December will be 22 °C- 28 °C (71.6 °F- 82.4 °F). We suggest you swim at noon time, because it is a little cold for you to swim in the morning or evening. Bye the way, some clothes like a light knitted sweater, long trousers, T-shirt and short are recommended. A coat is also needed at night. Annie Wu replied on 2012-11-20
