Haikou Hainan Climate, Haikou Weather, Haikou Average Sea Water Temperature


Haikou, the provincial capital enjoys a sub-tropical climate with an average annual temperature of 20°C (68°F). Haikou spring (April till June) is hot with humidity, almost same temperature as Sanya, the only beach destination on Hainan Island, and the high summer temperatures bring heavy rain. Summer ( July-September) is a season of typhoons and rain storms. October & November is very nice in Haikou, warm and dry. But in winter it can be very chilly with high humidity from December till March. So in winter, Sanya is the best destination for your Hainan Holiday. In Caddie's option, it is better not to visit Haikou and its surrounding area in Winter (December till March), but come to Sanya.


Raining Season July till September is not too hot, actually the highest temperature is around 34 degrees. While the temperatures in Beijing, Shanghai, Guangzhou could be over 38 degrees. So basically speaking, Haikou is actually cooler than those big cities. With the help of tropical showers or typhoon, day temperature could easily drop down to 26-28 degrees. Typhoon could be a problem, but usually won't last more than 2 days. And normally after typhoon, it becomes very hot, and the sun is sharp shining.


Haikou’s casual attitude makes packing a breeze. From March till November, shorts, T-shirts are usually all that is needed. For December and February especially during the evening, you need to prepare long pants and coat. Sun blocks, sandals, sun glasses are the must for you holiday in Haikou. Umbrella is not requested as you could get from the hotels/resorts you stay.
