Haikou Weather in May

Haikou Xixiu Beach

The rainy season starts from May, with a total rainfall of 183 millimeters (7.2 inches) and the number of rainy days at 16 for the month. The average temperature is 28.1°C (82.6°F), with a minimum temperature of 24.2°C (75.6°F) and a maximum temperature of 32 °C (89.6°F).

May marks the beginning of summer, with the temperature and rainfall increasing continually. And May is when typhoons begin to appear. Summer clothing like T-shirts and a light jacket are enough for the month, and bring a light coat or a cardigan for early morning or evening coolness. Ultraviolet radiation is a little stronger since the sun shines brighter, so bring sunscreen to protect your skin. Since rainfall is frequent, bring an umbrella. May is the peak travel season, and you can expect higher hotel rates and crowded tourist attractions. If you plan to visit Haikou during May, book in advance. See our Haikou Tours.
