Brief introduction to Climate in China

China Climate in General
In China, a vast land spanning many degrees of latitude with complicated terrain, climate varies radically. China has a variety of temperature and rainfall zones, including continental monsoon areas. In winter most areas become cold and dry, in summer hot and rainy.

Five Temperature Zones
Temperatures vary a great deal. Influenced by latitude and monsoon activities, in winter, an isotherm of zero degrees traverses the Huaihe River-Qinling Mountain-southeast Qinghai-Tibet Plateau. Areas north of the isotherm have temperatures below zero degrees and south of it, above zero. Mohe in Heilongjiang can hit an average of 30 degrees centigrade below zero, while the temperature of Sanya in Hainan Province is above 20 degrees. In summer, most of areas are above 20 degrees centigrade despite the high Qinghai-Tibet Plateau and other mountains such as Tianshan. Among these hot places, Turpan Basin in Xinjiang is the center for intense heat at 32 centigrade on average.

Cold-Temperate Zone: north part of Heilongjiang Province and Inner Mongolia (Representative city: Harbin)

Mid-Temperate Zone: Jilin, northern Xinjiang, and most of Heilongjiang, Liaoning, and Inner Mongolia (Representative cities: Beijing, Shenyang, Dalian, Urumqi, Hohhot, Dunhuang, Lanzhou)

Warm-Temperate Zone: area of the middle and lower reaches of the Yellow River, Shandong, Shanxi, Shaanxi, and Hebei Province (Representative cities: Xian, Taiyuan, Luoyang, Jinan, Qingdao, Zhengzhou)

Subtropical Zone: South of isotherm of Qinling Mountain-Huaihe River, east of Qinghai-Tibet Plateau (Representative cities: Shanghai, Guangzhou, Hong Kong, Macau, Guilin, Hangzhou, Suzhou, Kunming, Dali, Lijiang, Chengdu)

Tropical Zone: Hainan province, southern Taiwan, Guangdong, and Yunnan Province (Representative cities: Haikou, Sanya)

Plateau Climate Zone: Qinghai-Tibet Plateau (Representative city: Lhasa)

In summer, a southeast monsoon from the western Pacific Ocean and a southwest monsoon from the equatorial Indian Ocean blow onto the Chinese mainland. These monsoons are the main cause of rainfall. Starting in April and May, the summer rainy season monsoons hit the southern provinces of Guangdong, Guangxi, and Hainan. In June, the rains blow northward, and South China gets more rainfall with the poetic name, plum-rain weather, since this is the moment when plums mellow. North China greets its rainy season in July and August, says farewell in September; gradually in October the summer monsoons retreat from Chinese land. Eastern China experiences many climate changes, while the northwest area is a non-monsoon region.

Northern winters, from December to March, can be extremely cold. Beijing may experience temperature of -20C at night, dry and no sun. Further north, -40C are not uncommon, and you'll see the curious sight of sand dunes covered in snow.
During the summer, from May to August, temperatures in Beijing can hit 38C (100F), coinciding with the rainy season for the city.
The best time for visiting the north is spring and autumn. Daytime temperatures range from 20C to 30C (68F to 86F) and drop a lot at night. Precipitation is 6370cm (25-28 inches) per year.

The Yangtze River valley has long and humid summer with high temperatures from April to October. The city of Wuhan, Chongqing and Nanjing on the Yangtze are China's three famous 'furnaces'.
Winters there, with temperatures dropping well below freezing, can be as cold as in Beijing, particularly as there is no heating in public buildings to the south of the Yangtze River.
It can also be wet and miserable at any time apart from summer. Since it is impossible to choose an ideal time to visit, spring and autumn are probably best. Precipitation averages around 76 cm (30 inches) per year.

Near Guangzhou, the summer is a season of typhoons between July and September. Temperatures can rise to around 38C. Winters are short, between January and March. It's not as cold as in the north, but you'd better bring warm clothes with you while visiting.
Autumn and spring can be good times to visit, with day temperatures in the 20C to 25C (68F to 75F) range. Sometimes, it can be miserably wet and cold, with rain or drizzle. Precipitation averages 76 cm (30 inches) per year.

It gets hot in summer, dry and sunny. The desert regions can be scorching in the daytime. Turphan, which sits in a depression 150m below sea level, is referred to as the 'hottest place in China' with maximums of around 47C.
In winter this region is as severely cold as the rest of northern China. Temperatures in Turphan during winter are only slightly more favorable to human existence.
This area of China climate experiences little rain, and as a consequence, the air is very dry. Summers, however, can exceed 40C, while winters may drop to -10C. Precipitation averages less than 10 cm (4 inches) per year.

Undoubtedly, Tibet is one of the harshest places for human existence. It is cool in summer but freezing cold in winter. In Lhasa, the mildest city in Tibet, temperature may exceed 29C in summer while plummeting to -16C in winter!
Sun radiation is extremely strong in Tibet. The sunlight in Lhasa is so intense that the city is called Sunlight City. The thin air can neither block off nor retain heat so that the temperature extremes can be met in daytime and the same night respectively in Tibet. However it is not impossible to visit the holy snow land. April to October is the best time to visit Tibet, out of the coldest months, which are from December to February usually.
The average temperature in north Tibet is subzero and winter arrives in October until the following May or June. July and August are the best time to visit the area, enjoying warm temperature, intense sunshine, beautiful scenery and festive events.
May, June and September is the tourist season in east Tibet. In winter, roads are all blocked by heavy snow. Landslides and rock falls frequently occur, which will make travel difficult.
South Tibet is balmy during May to October. During the period, there are also great festive events held. Hence it is the best time to visit Lhasa, Shigatse and Nyingchi.
Most annual rainfall comes in the rainy season, which starts from June to September. Usually it rains at night in Lhasa, Shigatse and Chamdo area. The rainfall may block roads and make travel difficult but the scenery at the time will be the best. From November to the coming May, the wind blows often.
