Travel to Sanya, Hainan around February 15. I wonder what the weather is like there. Is it cold to swim in the sea at the present temperature? Is it sunny? Do you want to wear sunscreen?

Don't be afraid of tanning if you want to swim. If you are really white, you won't get a tan. Swimming in Sanya in February, the sea temperature is about 20 degrees, which is a little cold, but we northerners are not afraid. If you are really afraid of tanning, you can just put a sunshade and shawl long pants.

Dadonghai is crowded with people, and it is also very lively at night. In the evening, you can swim, listen to foreigners singing and have some coffee and beer.
