Yangsan city in South Korea recorded a daytime high of 42.5 °C on Aug. 2, setting a new national temperature record [1, 2].
This extreme spike marks a critical escalation in regional weather patterns, as the city has now experienced five consecutive days with temperatures exceeding 40 °C [1]. The event signals an intensifying trend of extreme heat across the South Gyeongsang Province.
Meteorologists attribute the record-breaking heat to a combination of the area's basin geography and a persistent heat dome [3]. These factors worked together to trap hot air over the region, intensifying the temperature in the Jungbu-dong area of Yangsan [2].
Residents described the conditions as unprecedented and physically grueling. Kim Jun-seok, a resident of Jungbu-dong, said this is the hottest summer he has ever experienced in his life. He noted that he began sweating immediately after showering and had never seen temperatures reach 42 °C [1].
Other locals reported that the heat made simple tasks nearly impossible. One resident said that waiting for a traffic signal was an ordeal because it felt as though their legs were burning [2].
Local authorities continue to monitor the heat dome's movement. The record 42.5 °C reading is now the highest temperature ever observed in the meteorological records of South Korea [2].
“this is the hottest summer I have ever experienced in my life”
The intersection of a heat dome and basin geography creates a 'pressure cooker' effect, where heat is trapped and amplified. This national record suggests that traditional infrastructure and public health strategies in South Korea may need to be reassessed to handle new, higher thermal extremes that exceed previous historical benchmarks.
