Climate and Weather
Haikou lies in the fringe of north low latitude tropical area with a monsoon tropical marine climate. It is warm in spring with insufficient rain, hot in summer with an abundance of rain, with excessive typhoon and torrential rain in autumn and cold in the winter. All around the year, Haikou is endowed with long sunshine time, with an annual average of more than 2000 hours; the average temperature is 23.5 degrees Centigrade, with the maximum of about 28 degrees Centigrade and minimum of about 18 degrees Centigrade. Hainan’s most popular season is, of course, Spring Festival, when legions of mainlanders shuddering from sub-zero winter temperatures spend Chinese New Year on the invitingly temperate beaches of the tropica island.
