Hainan weather reviews

Masha, May 2023
It is very hot in Hainan during this period, on average +33°C during the day, but it can be unbearably stuffy up to +38°C. For people who cannot tolerate such temperatures, it is better to choose a different season for the trip. It also rains quite often. Nice beach, quite a long shallow coastline, along a lot of water activities. The water reaches +29°C, which is prohibitively high. Only in the evening the heat drops to +27°C, and it becomes possible to walk around the evening city.
