Is it appropriate for Hainan to wear a flowered skirt in June?

Suitable. Because the temperature in Hainan in June is around 30℃, the weather is very hot, especially at noon, the temperature will reach above 30℃, so it is more appropriate to wear floral skirts in Hainan in June. When traveling to Hainan, you should bring sunscreen. The ultraviolet radiation in Hainan Island is very strong. To avoid sunburn, you should also wear sunglasses and an umbrella.
