On October 8, as employees returned to work after the holiday, they were welcomed by the first day of the Cold Dew solar term, which brought weather perfectly in tune with the new season. Following the passage of a weak cold front, forecasters predict that another front will move into northern China from today until October 10, causing temperatures to dip. However, starting October 11, most regions will see a gradual increase in temperatures, shifting from below-average to above-average conditions in both the north and south.

As the cold air settles in, light precipitation is expected to sweep across northern China from west to east over the next three days, but it won’t last long. Meanwhile, the southwest will remain under cloudy and rainy skies, and residents in certain areas should stay alert for potential geological hazards.

The previous day was the last day of the National Day holiday, and the arrival of cold air resulted in cooler temperatures for areas such as southern Hebei, northern Henan, northern Shandong, and many parts of southern China. Many regions are now experiencing maximum temperatures near or even below seasonal averages, with some areas in Jiangnan and Jianghuai having their coolest temperatures since autumn began.

With the onset of the Cold Dew solar term—autumn’s final solar term—activity from cold air is set to increase. The new weak cold front is predicted to bring a drop in temperatures by 3 to 6 degrees Celsius to parts of northwest China, North China, and Northeast China, accompanied by north winds reaching level 4 to 5, with gusts hitting levels 6 to 8.

Overall, while this cold front is expected to have a limited impact, northern regions will still feel its effects. Starting on the 11th, temperatures will rebound across most of China, shifting from cooler to warmer.

Although the cold air will be relatively weak in the upcoming three days, notable temperature differences between day and night—often exceeding 10 to 15 degrees Celsius—are anticipated in many areas north of Jiangnan. Residents are encouraged to dress warmly in the mornings and evenings.

Looking ahead, many parts of the southwest will continue to experience rain, while light precipitation is expected to develop in the north. Since October began, most regions in China have recorded below-average rainfall, but southeastern Tibet and northwestern Yunnan have seen precipitation levels that are more than double the norm for this time of year. Heavy rain or torrential downpours have impacted western Yunnan, northeastern Guangdong, southern Hainan, and coastal areas of Fujian, with extreme rainfall reported in sections of Yunnan and Taiwan.

For the next three days, rainfall in certain southern regions is expected to decrease, transitioning to clearer skies with occasional clouds, while northern areas will experience weak precipitation due to the cold front, expected to be brief. According to the Central Meteorological Observatory, today’s forecast includes light to moderate rain in southern Gansu, Shaanxi, central and southern Inner Mongolia, and parts of Sichuan, Yunnan, Guizhou, eastern Jiangnan, Hainan Island, and Taiwan. Areas in southwestern Sichuan and central-northern Yunnan may see significant rainfall, including localized heavy rain. Moreover, regions in southwestern Xinjiang, northeastern Tibet, and southwestern Qinghai may witness light snowfall or mixed rain and snow.

Tomorrow, light to moderate rain is anticipated in central and southern Gansu, southern Shaanxi, central and eastern Inner Mongolia, as well as Heilongjiang, central and western Jilin, Liaoning, and parts of northern Hebei, northern and central Shandong, Sichuan, Yunnan, and Guizhou. Some southwestern Sichuan and southeastern Tibet regions may experience heavy or localized torrential rain, while eastern Tibet and central-eastern Qinghai could see light snowfall or mixed precipitation.

On the following day, light to moderate rain is forecast for southern Gansu, central Heilongjiang, eastern Jilin, Sichuan, Chongqing, and portions of Yunnan and Guizhou. Heavy rain may occur in some southwestern Sichuan and southeastern Tibet regions, while northeastern Tibet, central and southern Qinghai, and northeastern Inner Mongolia could experience light snowfall or mixed precipitation.

The China Weather Network has issued warnings that frequent rains could pose significant meteorological risks of geological hazards in southeastern Tibet, northwestern Yunnan, and southern Sichuan, urging the public to take preventive measures. Additionally, areas such as southern Hebei, northern and eastern Henan, southeastern Shanxi, and southwestern Shandong may encounter dense fog this morning, with visibility dropping below 200 meters in some locations, potentially complicating travel plans for holiday returnees. Caution is advised for safe driving in these conditions.
