I plan to visit Sanya in the next few months. What is the weather in September and October? Where is the green island hotel?

According to the previous weather statistics, the temperature of these two months doesn't have big difference. It's 77 F to 94 F. And there are mainly cloudy days. The climate is very hot. Sometimes, several showers can bring cool and comfortable feelings. Summer clothes are enough for you to prepare. In addition, you'd better bring sunblocks.
But I cannot find the hotel you mentioned. Maybe you need to check the hotel name again.

Thanks!
