What to wear to Sanya, Hainan in early March?

I am a college student studying in Sanya. March 10, the sun is around the equator, and the north latitude of Sanya 18 degrees. It is conceivable that the sun is quite big. In fact, Sanya always has the sun at noon, unless it is cloudy.

Answer your questions in turn:

1. You can wear suspenders, but it may not work in Haikou, and it's a little cold. Sanya is absolutely ok.

2. You need to apply sunscreen, and you can sweat with short sleeves.

You can swim in the sea. There are quite a lot of tourists in March.

You must take a coat, the medium and thin one will do. The weather in Hainan may not be cold, but it will be a little cold at night.

There will be a rainy season in Hainan in spring, so it is recommended to look at the weather forecast before coming. It's not fun when it rains.

Finally, I suggest that you must pay attention to property management, not that there are many thieves in Hainan. The bag must be placed on your chest (especially in buses and public places), and you must pay attention to safety when going into the sea, and don't go too deep. Because some seabed slopes are relatively large. It is best not to blindly buy pearl necklaces and the like. It is recommended to buy in a regular boutique.
