The Hong Kong Observatory reported that October 2026 was the warmest since the city began recording temperatures in 1884, with the average temperature standing at 27.6 degrees Celsius. The mean maximum and minimum temperatures also reached record levels at 30.5 degrees and 25.8 degrees Celsius, respectively. The unusually warm conditions were attributed to the ongoing El Niño phenomenon and a weak northeast monsoon, with the Observatory also noting the role of climate change. A fresh to strong northeast monsoon is expected to impact the city in the coming days, potentially bringing a slight decrease in temperatures early next week.
The Observatory attributed the warm temperatures to several factors, including the ongoing El Niño and the weak northeast monsoon. Despite the El Niño affecting weather globally, Hong Kong was particularly impacted, leading to a notable rise in temperatures. The weak northeast monsoon also played a significant part in the warm conditions. Additionally, the role of climate change was highlighted as a contributing factor to the warm October.
Going forward, residents and authorities are expected to prepare for potential shifts in weather patterns due to the northeast monsoon. This system typically brings cooler air and could provide temporary relief from the high temperatures. However, the long-term outlook remains concerning, with climate change expected to continue affecting weather patterns in the region. Authorities are likely to issue advisories and preparations for any potential changes in weather conditions in the coming days.
