Cold Front Sweeps Central and Eastern China, Pushing Temperatures to New Seasonal Lows
A cold air mass is moving across central and eastern China on October 4-5, driving temperatures in multiple regions toward new lows since the start of autumn and prompting a blue-level gale warning from the National Meteorological Center, Xinhua News reported. The sharp cooldown arrives mid-way through China’s week-long National Day holiday, complicating travel and tourism across a wide swath of the country.
According to Xinhua, the cold front follows an initial surge that reached China on October 3, when parts of Gansu and Inner Mongolia saw temperatures fall by more than 10°C, with some areas dropping over 15°C.
Wind and Temperature Drop
Over October 4-5, the cold air continues to push east and south. Successive northerly winds of Force 4-6 are forecast across central and eastern Inner Mongolia, North China, the Huang-Huai region and the Jiang-Han basin, with gusts of Force 7-9 and locally above Force 10 in high-altitude mountainous areas, according to the National Meteorological Center’s weather bulletin.
Temperatures are expected to fall 4-6°C regionally, with some areas seeing drops of 8-10°C. After the cooldown, maximum temperatures in much of Northeast China will stay below 15°C, while eastern Northwest China and North China will hover around 20°C. The cities of Changchun, Shenyang, Beijing and Tianjin may record their lowest daytime highs since the start of autumn on October 4.
The South Catches Up
As the cold air pushes south and combines with persistent rain, much of Southwest China’s east and the Jiangnan region will see maximum temperatures of only around 20°C, while the 30°C-plus zone across South China shrinks significantly. From October 5-7, minimum temperatures across much of the south are forecast to hit new post-autumn lows, with Fuzhou, Guangzhou and Nanning dropping below 20°C for the first time this autumn, and Nanjing and Hefei falling to around 10°C.
A weather bulletin from the National Meteorological Center confirms that southern rain will gradually weaken and largely cease by October 6, though clear skies will bring pronounced nighttime radiative cooling.
Marine and Fog Warnings
Beyond the landmass, eastern and southern sea areas will see Force 6-8 northerly winds with gusts up to Force 9 from October 4-8. Morning fog is also forecast for parts of southern Henan, eastern Hubei, southern Anhui and central-southern Chongqing, with localized visibility under 200 meters. The same bulletin notes that Typhoon Caiyun, the year’s 27th typhoon, is affecting south-central Japan with moderate-to-heavy rain and strong winds, a separate system from the mainland cold front.
Provincial warnings have been issued in parallel. Jiangxi has issued a blue gale warning and an orange rainstorm warning, Shanxi a blue gale warning, Chongqing a yellow dense-fog warning, and Inner Mongolia a blue frost warning.
Holiday Travel Disruption
The timing is significant: the cold front coincides with the October 1-7 National Day Golden Week, China’s busiest travel period. An earlier cold air mass on October 2 had already brought strong rain to Guizhou, Hunan, Guangxi, Guangdong and Fujian, according to a report carried by Tencent News, with advisories stressing the impact on holiday travel, tourism safety and the autumn harvest.
China’s meteorological services are warning of secondary disaster risk. “Southern rain will weaken today, but geological disasters have a lag — Guizhou, Hunan and other places have accumulated heavy rainfall and must guard against flash floods, landslides and other secondary disasters,” the China Weather Network advised via Xinhua. “As it is the National Day holiday, the public should take care to avoid rain and slipping, and pay attention to traffic safety when travelling.”
The agency also urged residents to adjust clothing to temperature changes, take windproof and coldproof measures, and—during high-wind periods—avoid billboards, temporary structures, old buildings and glass curtain walls. Indoors, it advised closing doors and windows tightly and bringing in flowerpots and other loose objects from balconies and windowsills.
Outlook
Relief is in sight. According to the National Meteorological Center, the cold air will weaken after October 6, and temperatures across most of the country will steadily recover. Until then, the combination of falling temperatures, strong winds and lingering southern rain will keep much of central and eastern China notably cooler than the season’s norm—a sharp reminder that autumn has arrived.
What to watch next: Whether the southern minimum temperatures set on October 5-7 approach all-time October records, and how the cooldown affects late-holiday travel as millions return home.
