China Faces Rain, Snow and Falling Temperatures Through October 21

What changed

Rain and snow will remain frequent across northeastern China and the middle and lower reaches of the Yangtze from October 18 to 20. Parts of northeastern Inner Mongolia and northwestern Heilongjiang could see heavy or exceptionally heavy snow today, while another cold-air outbreak from October 19 to 21 is expected to push temperatures down across central and eastern China.

The forecast calls for:

• 4–8°C cooling across much of central and eastern China, with drops of 10–12°C in some areas.
• Strong northerly winds north of the Yangtze, with gusts reaching 6–8 on the Beaufort scale.
• The 0°C line reaching parts of Liaoning, Hebei, Shanxi, Shaanxi and Gansu on October 21–22.
• Temperatures below freezing in Taiyuan and Yinchuan on October 21; Hohhot and Xining could fall to about -5°C.

Why it matters

This is a weather pattern with two moving parts: persistent precipitation in the northeast and Yangtze basin, followed by a broader freeze spreading south. That combination can make travel harder, especially where heavy snow arrives while temperatures are falling.

The rain belt will shift away from North China and the Huanghuai region, but central and southern areas will still see repeated rain. Parts of Jiangsu, Anhui, Hubei, Hunan, Chongqing, Guizhou and Yunnan may receive moderate to heavy rain through October 20, with local downpours.

The cold will also reach cities farther south than the first snow zones. Hefei and Nanjing are forecast to fall into single-digit temperatures on October 21. For households and local services, the practical change is a sharp turn from autumn rain to colder, windier conditions over only a few days. Any disruption from flooding, snow or transport delays will depend on how severe the weather becomes locally.
