February 5, China entered the beginning of spring. Previously, many localities across the country recorded unusually warm weather. In the north, including Beijing and Tianjin, the daytime temperature increased to about 10 degrees Celsius. In the south, the common temperature is above 15 degrees Celsius, even in some places up to nearly 20 degrees Celsius.
However, this short warm spell was quickly replaced when a strong cold air mass from the North poured down. From February 6-7, temperatures in central and eastern China are expected to drop from 6-10 degrees Celsius. The northeast region alone has places dropping above 20 degrees Celsius, bringing many localities back to severe cold and harmful cold after only 1 night.
Weather forecast experts say that by dawn on February 8, the zero-degree Celsius equatorial line may deepen southward, reaching northern Fujian and Hunan - a rare occurrence in the early spring period.
This cold air mass moves very quickly, in a north-east direction, the temperature drop is very strong, meeting the standard of strong cold air in many provinces" - Mr. Tran Dao, Chief Forester of the National Meteorological Center of China, assessed.
Not only causing deep cold, the cold air mass also brings heavy rain and widespread snowfall. Many areas in eastern China will witness rain turning into snow or snowfall, some places may experience local blizzards. Further south, widespread rain covers many provinces and cities.
According to Weather China, this bad weather affects more than 15 provinces and cities, right at the peak travel time of the 2026 Lunar New Year. The deep drop in temperature, accompanied by snowfall, is assessed to cause disruption to road, rail and air traffic.
Faced with complicated weather developments, the Ministry of Emergency Management of China has requested central and eastern localities to proactively implement response plans. The focus is placed on ensuring traffic safety, stabilizing power supply and providing timely support to people during the severe cold days on the occasion of the Kitchen Gods.
