China Geography & Climate
Geography
China covers about 9.6 million square kilometres, spans five geographic time zones while officially using one, and descends in three great steps from the Tibetan plateau in the west to the coastal plains in the east.
The three steps
The highest is the Tibetan plateau, averaging above four thousand metres and rimmed by the Himalaya, Karakoram and Kunlun — the world’s highest and largest plateau, and the source of the rivers that supply much of Asia. The middle step holds the basins and plateaux of the interior: the Tarim with the Taklamakan desert, the Gobi, the loess plateau, the Sichuan basin. The lowest is the eastern plains, where the great majority of the population lives.
Two rivers
The Yangtze, at about 6,300 kilometres the longest in Asia, divides north from south in climate, agriculture and diet. The Yellow River, carrying more sediment than any river on earth, built the north China plain and repeatedly destroyed it — it has changed course catastrophically many times.
Mountains and karst
Around two thirds of the country is mountain, hill or plateau. The limestone of Guangxi and Guizhou has weathered into the karst towers of Guilin and Yangshuo, among the most recognisable landscapes anywhere.
The dividing line
The Qinling mountains and the Huai river mark the boundary between the wheat-growing, dry, cold north and the rice-growing, wet, subtropical south. It determines the food, the architecture and, historically, whether buildings had central heating.
Coast and desert
Fourteen thousand kilometres of coastline in the east; in the far west, the Taklamakan, one of the largest shifting-sand deserts in the world, which the Silk Road went around rather than through.

Climate Patterns
China spans nearly fifty degrees of latitude and five thousand metres of altitude, so it contains almost every climate type on earth. Three broad zones cover most of it.
The east and north
A monsoon-influenced continental climate. Beijing has cold, dry, windy winters well below freezing and hot, humid summers above 30°C, with most of the rain falling in July and August. Harbin, in the far north-east, drops below −20°C and builds an ice festival on it.
The south
Subtropical and wet. Guangzhou, Hong Kong and Guangxi are humid year round, mild in winter, and hot from April to October, with the plum rains in early summer and a typhoon season from July to September on the coast.
The west
The Tibetan plateau is cold, dry and intensely sunny at altitude, with enormous swings between day and night and snow possible in any month. Xinjiang’s basins are extreme desert — Turpan is among the hottest places in the country in summer and freezing in winter.
The north-south line
Historically, buildings north of the Qinling-Huai line received state central heating and those south of it did not. The result is that winter indoors in Shanghai or Chengdu can feel colder than in Beijing, and visitors are regularly caught out by it.
Air quality
Northern cities suffer worst in winter, when heating demand peaks and still conditions trap pollution. Air quality has improved substantially over the last decade but remains variable; the daily index is widely published and worth checking if you have a respiratory condition.
