Recently, under the influence of warm and humid air currents, small droplets of water appear on indoor walls, floors, and ceilings, dripping continuously with the slightest touch in Guangdong homes.

Many residents of Guangdong have reported that the "Huinan" phenomenon in 2024 is more severe compared to previous years, with some even needing umbrellas while sleeping. Door couplets outside homes have been soaked, leaking out a red liquid, resembling eerie symbols, creating a frightening atmosphere. Additionally, fingerprint locks on some residents' doors have malfunctioned due to water exposure, rendering them unable to enter their homes. Even potato chips have turned into sponges, absorbing water and becoming soggy. Electrical switches inside homes are also affected by water ingress, causing potential electric shocks with any accidental contact.

"Huinan" is a term used to describe a meteorological phenomenon in southern China, usually occurring in spring when temperatures begin to rise and humidity drastically increases. During "Huinan," the air humidity approaches saturation, resulting in damp conditions everywhere.

According to the Guangdong Meteorological Bureau, the temperature in the province continued to rise on the 5th, with the maximum temperature exceeding 30°C. Meanwhile, the "Huinan" phenomenon intensified further, covering almost the entire province, with relative humidity in Guangzhou ranging from 90% to 99% on that day. However, "Huinan" is expected to end by the 6th. The Guangdong Meteorological Bureau predicts that from the 6th to the 7th, a moderate cold air mass will affect the province, causing temperatures in most cities and counties to drop by 4°C to 6°C, effectively alleviating the "Huinan" phenomenon.

近日，在暖湿气流影响下，广东出现回南天，室内墙上、地上、天花板上全是小水珠，一刮就流水，变成了“水帘洞”。
许多广东名居民表示，2024年的“回南天”现象与往年相比较为严重，甚至睡觉时都需要打伞。家门口的对联被泡坏，流出一地的“红色液体”，看上去变成了鬼画符，感觉很恐怖。另外，有居民家的指纹锁因为布满了水，失去了感应，无法进门。开封的薯片也变成了吸水海绵一样，变得软乎乎全是水。家里的开关因为进水，出现了漏电的情况，一不小心就会触电。
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。
据广东省气象局介绍，全省5日气温继续上升，当日最高气温已超30℃，同时，回南天现象进一步加剧，全省几乎在回南天笼罩下，广州当日相对湿度在90%至99%之间。不过回南天或于6日结束。据广东省气象局预计，6日到7日，中等强度冷空气将补充影响该省，大部分市县气温下降4℃至6℃，届时将有效缓解回南天现象。
