The rainy season comes in September and October. There is a possibility of typhoons in these months. There is no need to worry about inclement weather, though. It hardly ever rains for the whole day and showers tend to be cool and refreshing.

Hainan’s typhoon warning system is up to the minute and its buildings are designed to offer protection from wind. Some people specifically await a typhoon so that they can observe nature’s raw power from the comfort and safety of the their hotel room.
