Under the influence of warm and humid air currents, southern China's Guangdong Province experienced a phenomenon known as "Hui Nan Tian", or "Returning South" in English on March 5.

Residents found their ceilings, walls, glass, and floors covered in droplets of water, so much so that a light touch would cause water to trickle down.

Some residents resorted to using hairdryers to tackle the issue, turning their homes into instant waterfalls as water cascaded down from the ceilings.

"Hui Nan Tian", a term referring to a weather phenomenon in southern China, typically occurs in spring when temperatures begin to rise and humidity sharply increases. When "Hui Nan Tian" occurs, the air becomes saturated with moisture, leading to a damp and humid environment everywhere.

On March 6th, meteorological staff at the Guangzhou Meteorological Observatory explained that during the transition from winter to spring, sudden warm-ups after cold air masses can trigger the occurrence of "Hui Nan Tian".

Due to significant temperature fluctuations during the winter of 2024, this episode of "Hui Nan Tian" was particularly severe. The staff urged residents to keep doors and windows tightly closed, and suggested implementing measures such as dehumidification and heating within homes to mitigate the effects of the weather.

3月5日，在暖湿气流影响下，广东出现回南天，居民家的吊顶，墙壁，玻璃和地板上布满了水珠，轻轻一碰就会出现流水，有居民用吹风机去吹屋顶，家里变瞬间变成了水帘洞一样，水从屋顶哗哗往下流。
回南天（简称回南），是对中国南方地区一种天气现象的称呼，通常指每年春天时，气温开始回暖而湿度猛烈回升的现象。当“回南天”出现时，空气湿度接近饱和，到处是湿漉漉的景象。
3月6日，广州市气象台工作人员介绍了，冬春之际，在冷空气过后，天气突然回暖，就会出现“回南天”，因为2024年冬天大冷大暖交替明显，导致此次“回南天”较为严重。广州市气象台工作人员呼吁居民紧闭门窗，家中也可以采取抽湿升温措施。
