Hainan is warm all year — the question is humidity and rain, not cold.
Best season
November to April: sunny, dry and 22–28°C — the peak season for beaches. May to October is hot and humid with afternoon showers; July to September is typhoon season.
What to pack
Light clothes year-round, sunscreen, swimwear, a light rain jacket in summer, and a light layer for winter evenings.
Sea conditions
Swim only at patrolled beaches and respect red-flag warnings — currents on some bays are strong.
Tip Book refundable flights if traveling in typhoon season and keep an eye on weather alerts.
