Hong Kong is currently facing a significant challenge as the air becomes saturated with extreme levels of humidity. The Hong Kong Observatory has predicted a continuous 100% relative humidity until Wednesday. This unusual weather phenomenon has resulted in a unique situation within the city's buildings, with walls and ceilings appearing to "sweat" as if they were cave stalactites.
According to the latest reports from the Observatory, a warm and humid southerly airstream is dominating the Guangdong coastline. As a result, visibility across the Hong Kong harbor has significantly dropped, occasionally falling below 5000 meters at night. Meanwhile, a pressure build-up in the northern parts of Guangdong indicates the approach of a northeast monsoon, which is expected to bring cooler and drier air to the coastal areas by tomorrow.
The forecast for the immediate future predicts mostly cloudy skies with scattered showers. Initially, foggy conditions will prevail, with temperatures hovering around 24 degrees Celsius before dropping to approximately 19 degrees tomorrow night. The prevailing southerly winds will shift to moderate northerlies, which will be stronger offshore.
Residents have been expressing their concerns about the impact of the high humidity, sharing images on social media platforms such as the Tseung Kwan O community Facebook page, showcasing the dew-covered conditions in their homes, with corridors, ceilings, and walls drenched in condensation.
The upcoming northeast monsoon is expected to alleviate the current humidity, with temperatures anticipated to drop to around 16 degrees Celsius by Thursday morning. The region will experience cooler and windier conditions in the following days, with urban temperatures not exceeding 20 degrees until early the following week. This coincides with forecasts of an upper-air disturbance that may bring unsettled weather to Guangdong.
Due to the dense humidity, electronic devices like televisions have been reported to malfunction, likely due to moisture infiltrating the components and causing short circuits. Lo Kok-keung, a retired engineer from the Hong Kong Polytechnic University, advises residents to place dehumidifiers near their electronics until the components are dry to mitigate the impact of the humidity.
These moist conditions, unique to the coastal regions of southern China during cold spells, occur when buildings and floors, cooled by cold air, are quickly enveloped by warm and moist air. This leads to condensation forming water droplets on cooler surfaces, resulting in the observed "sweating" effect on walls.
Residents continue to express their concerns about the moisture, sharing images on social media platforms to highlight the dew-laden conditions in their homes, with corridors, ceilings, and walls covered in condensation.

香港面临高湿度和饱和空气的困扰
香港目前面臨一個重大挑戰，空氣中的濕度達到極高水平，使空氣飽和。香港天文台預測，這種異常天氣狀況將持續到周三，相對濕度將一直保持在100%。這種不尋常的天氣現象導致城市建築物出現了一種獨特的現象，牆壁和天花板開始像洞穴中的鐘乳石一樣“出汗”。
根據天文台的最新報告，目前廣東沿岸地區受到溫暖潮濕的南風影響。這導致香港海港的能見度大幅下降，夜間有時甚至低於5000米。與此同時，廣東北部地區出現的壓力增加表明東北季風即將來臨，預計明天將為沿海地區帶來更涼爽和乾燥的空氣。
未來的預報顯示，天空大致多雲，分散陣雨。最初將有霧氣，氣溫約為攝氏24度，明晚預計下降到約攝氏19度。主導的南風將轉為中等偏北風，離岸風勢較強。
居民對潮濕氣候的影響表達了關注，他們在社交媒體平台上分享了照片，展示了家中走廊、天花板和牆壁上的凝露情況。
預計即將到來的東北季風將有助於減輕目前的濕度，預計到周四早上氣溫降至約攝氏16度。該地區在接下來的幾天將會出現更涼爽和多風的天氣狀況，城市區域的氣溫直到下周初都不會超過攝氏20度。這與對廣東可能帶來不穩定天氣的上層氣體扰動的預測相吻合。
由於濕度高，電視等電子設備報告出現故障，可能是由於潮濕進入組件並引起短路。香港理工大學的退休工程師盧國強建議居民在組件變乾之前將除濕機放在電子設備附近，以減輕濕度的影響。
這種潮濕的環境條件在寒冷天氣時特別出現在中國南部沿海地區，當建築物和地板受到冷空氣的冷卻後，迅速被溫暖潮濕的空氣包圍。結果，冷卻表面上形成了水滴，導致牆壁出現“出汗”的效果。
