Hainan, like southern Taiwan and southern Yunnan, has tropical seasonal winds, year-round summer, and abundant rainfall, making it possible to achieve three or four harvests a year. And the south of the island is suited for growing coffee, rubber trees, and other tropical crops.
它與台灣南部、雲南的西雙版納，同樣地處熱帶季風區，四時皆夏，雨量充沛，稻作一年達三至四獲；南部則適合栽培咖啡、橡膠等熱帶作物。
