Haikou Weather in December

December weather

December is one of Haikou's best months for being outdoors. Days reach about 22°C, while evenings cool to around 18°C. Rain is limited compared with November, though showers still fall on about seven days. Humidity stays high, so the air can feel a little damp rather than crisp. You'll get some sunshine, but cloud is common too.

It's comfortable weather for walking Qilou Old Street, exploring the Hainan Museum or taking a stroll along Holiday Beach. The sea may feel cool for a long swim, and cloudy spells can dull beach views. If you're hoping for guaranteed blue skies, December isn't a sure thing.

Things to do and events

The Hainan International Tourism Island Carnival often takes place around late autumn and early winter, with events in Haikou. Dates and activities vary, so don't build your whole trip around it. Christmas isn't a public holiday in China, though you may spot seasonal decorations in shopping areas.

If you hate crowds, visit Qilou Old Street on a weekday. Its arcades offer shade if a brief shower rolls in, and you can stop for Hainanese chicken rice nearby.

Crowds and practical tips

December starts the comfortable winter travel season, and Haikou can feel busier than in the wetter summer months. It's not usually as crowded as the Lunar New Year period, which falls later in winter. Prices can rise as demand grows, especially around Christmas and New Year, but December isn't uniformly busy.

Travelling with kids? The mild days suit a visit to the Hainan Tropical Wildlife Park, though rain can still interrupt outdoor plans. For a dry break, head to the Hainan Museum. Check its opening days before setting out, as it closes on Mondays.
