When I go to Hainan at the end of March, what is the approximate temperature?

I am from Hainan, but the weather here is very hot, more than 30 degrees at the end of March, and the chances of typhoons and heavy rain are very few. The temperature difference between the two months is not much different, but the temperature will cool down a bit in mid-March, but it will recover soon, so you won't encounter it. Just dress according to the weather in July.
