On the morning of October 29, 2025, the Beijing Meteorological Service issued a yellow fog alert for several districts, including Daxing, Tongzhou, Chaoyang, Shunyi, Fangshan, and Fengtai. Visibility in some areas dropped below 500 meters, significantly impacting transportation and public safety. The National Meteorological Center also renewed the yellow fog warning at 6 a.m., indicating that foggy conditions would persist across Beijing and other parts of the country until noon. In southern Beijing, visibility was reported to be as low as 200 meters. Authorities advised the public to stay updated on traffic conditions, use public transportation, and exercise caution on the roads. Outdoor activities, particularly high-altitude work, were suspended for safety. Meteorologists predict that visibility will improve from late night into Thursday morning due to northerly winds. China’s four-tier weather warning system categorizes yellow as the third most severe level, following red and orange.
