Weather forecast in Sanya in March

Have you already left? It is hard not to rain these days. Sanya is very hot. It won't affect. But there was a shower on the evening of the 22nd. I suggest you travel to Hainan after Tomb-Sweeping Day. There are many people on May Day. You can come before that. It was still Tomb-Sweeping Day, but it didn't rain much afterwards.
