Yangsan, South Korea, recorded a daytime high of 42.5°C on Sunday, breaking the all-time observed maximum temperature for the third consecutive day [1].
This unprecedented spike in temperature signals a dangerous escalation in regional heatwaves, posing severe health risks to residents and challenging urban infrastructure. The record was officially logged at 1:26 PM KST on Aug. 2, 2026 [1, 2].
The current heatwave has persisted since July 29, 2026 [2]. For five consecutive days, Yangsan has seen temperatures exceed 40°C [1]. This trend follows a series of rapid record-breaking events: on July 31, 2026, the city recorded 41.4°C [1]. Prior to this current wave, the national record was 41°C, set in Hongcheon on Aug. 1, 2018 [1].
Other cities in the Gyeongsangnam-do province, including Changwon, Gimhae, and Gyeongju, also reported temperatures exceeding 40°C [1, 3]. The extreme conditions are attributed to two high-pressure systems surrounding the Korean Peninsula, combined with local topographic effects from the Gajisan and Sin-mountains [1, 2].
"The daytime high temperature in Yangsan, Gyeongnam, soared to 42.5 degrees," a YTN anchor said [1]. Reporter Jang A-young said the temperature is six degrees higher than the average human body temperature, describing it as a "murderous" heat [1].
Local authorities continue to monitor the situation as the high-pressure systems remain stationary. The persistent nature of the heat, five days of temperatures over 40°C, marks a significant departure from historical weather patterns in the region [1].
“Yangsan recorded a daytime high of 42.5°C on Sunday, breaking the all-time observed maximum temperature.”
The rapid succession of record-breaking temperatures in Yangsan suggests a compounding effect where high-pressure systems and local geography trap heat, preventing nocturnal cooling. This pattern indicates that previous historical benchmarks for South Korean summers are no longer reliable predictors for extreme weather events.
