What is the weather like in Hainan these days? What clothes are more suitable to wear?

In Haikou, it is still short sleeves, shorts and slippers. Hainan is an island on slippers, and Haikou is humid. I suggest you bring more short sleeves and slippers. If you want to live for a long time, you can go to the supermarket to buy some moisture-proof balls. Compared with inland cities, Haikou city is dirty and humid, but there are some beautiful scenery. Have a good time.
