Go to Sanya at the end of the month and watch the weather forecast. It rains every day.

The weather forecast in Hainan usually only reflects part of it. Thunderstorms have been reported every day in Haikou in the past two days, but it didn't rain when I stayed in Haikou. Actually, it's not a typhoon monsoon now, so it doesn't matter if it rains when I go out to play. It doesn't rain for long in Hainan, but usually it passes after a shower. Rainy Sanya has also avoided the fierce sunlight, which is a good thing in a way.
