Who knows what the weather will be like in Hainan on August-12? I plan to travel there. It is best for local people to introduce me and give me some suggestions. Thanks again.

Hainan is relatively cold these days, because I am now in Haikou, and there are showers every day due to the cold air these days. Now Hainan is rainy season and typhoon season, and the rainy days should last until about 14. If you like cool, it's appropriate to go out for a holiday now, but if you want to sunbathe, you may have to wait a few days for the cold air here to pass.
