Off Season (May-November)
If you prefer to have more of Haikou to yourself, then May to November could be a great time to visit.
It's the off-peak season, meaning the city and its surrounds are less crowded.
It doesn't mean that the welcome you receive will be any less warm. You're guaranteed a tropical smile all year round.
You may also find some great deals on hotels and tickets, as there is less demand compared to the busy, peak season.
You'll still be able to enjoy all the natural wonders of the destination, including all the coast has to offer, including the vast variety of water sports.
If you have children with you on holiday, a trip to the Wet 'n' Wild Haikou Water Park or Changying Wonderland is also always a winner.
It's also a good time of year to visit the mountains and one of the many volcanic clusters and parks.
By the end of the peak months, December to April, there can be heavy rainfall and, from October, typhoons occasionally hit the island, so make sure you do your homework about the optimum times to visit.
It may be off-peak season between May and November, but that doesn't mean you shouldn't come well prepared. Make sure you pack your summer clothes: short sleeves, shorts, sandals and sunglasses.
The sun is always strong in Haikou, so remember you sun protection too, to ensure you have a great time.
Plan your itineraries thoroughly, so you don't spend too much time in the heat. You'll also want to make sure you have lots of water with you, to keep you feeling refreshed.
