Weather: It is cool and comfortable in November. The average temperature is between 22 °C (71.6 °F)and 28 °C (82.4 °F). It is one of the best time traveling in Sanya because November is the slack season of tourism there.
Be aware: If you go to the beaches, sun-protection measures are still needed.
Clothes: A T-shirt and a pair of jeans are adequate for the day time. But a sweater or a light coat is necessary at early morning or evening because it is windy.
