Hong Kong experienced its hottest day on record Sunday, with temperatures reaching 36.9 degrees Celsius at the Hong Kong Observatory (HKO) headquarters. This extreme heat is attributed to a heatwave influenced by Tropical Cyclone Dolphin. The HKO headquarters in Tsim Sha Tsui is the official location for the city’s long-term temperature records. Sunday’s reading surpasses all previous high temperatures recorded since the start of record-keeping. The heatwave poses potential health risks for residents, urging precautions against heatstroke and dehydration. Authorities are monitoring the situation closely as the influence of Cyclone Dolphin continues. This record-breaking temperature highlights the increasing impact of climate change on the region.
