Hainan province lies at the southernmost tip of China, facing Guangdong province in the north across the Qiongzhou Strait, the Democratic Republic of Vietnam in the west across the Beibu Gulf, and Taiwan province in the east across the South China Sea. To the south and southeast it is bounded in the South China Sea by the Philippines, Brunei and Malaysia. Hainan has a land area of 35,000 square kilometers and a sea area of approximately 2 million square kilometers. Hainan Island is China's second largest island after Taiwan, with an area of 33,900 square kilometers.
A tropical maritime climate prevails in Hainan, bringing it all-year-round windy but warm days, abundant rainfall, clearly divided dry and wet seasons, frequent tropical storms and typhoons, as well as diversified climatic resources. Winterless Hainan Island has an annual sunshine time of 1,750 to 2,650 hours, a yearly average temperature of 23 C to 25 C, and an average annual rainfall of above 1,600 mm.
Hainan has numerous distinctive tourism resources. Sandy coasts take approximately 50 to 60 percent of its 1,528-kilometer coastline. The beaches are usually hundreds or thousands of meters wide, stretching gently into the sea with a slope of five degrees. Located alongside an unruffled sea, with crystal-clear seawater at the temperatures between 18 C and 30 C, in addition to bright and abundant sunlight, most of its beaches are good for swimming, sunbath, sand-bath and wind-bath almost all year round. Also along the eastern coastline are mangroves and coral reefs that are unique to tropical coastal areas.
Hot springs are widely dispersed on the island. Due to their low mineralization, high temperature, big flow and high quality, many of the hot spring waters have curative effects. Furthermore, the hot springs are all located in places with attractive landscapes, providing excellent conditions for developing holiday resorts for combined purposes of tourism, sightseeing, convalescence, and scientific researches.
