I plan to travel to Hainan next week. What's the weather like there and what clothes are suitable for me to wear?

Now Hainan has gradually entered the summer. The temperature is about 30 degrees during the day, and the sea breeze is cool at night. This season is not too hot to travel. You can bring a cotton short-sleeved vest and sweat-absorbent pants, but don't forget to bring a slightly thicker coat. It's still cold after eight days of rain. The main thing is to take good sun protection measures and be sure to bring an umbrella. It often rains recently.
