South Korea recorded its highest temperature ever on Sunday, Aug. 2, as a severe heatwave swept across the peninsula [1, 2].
The event marks a critical escalation in regional climate patterns, with authorities issuing emergency warnings to protect residents from life-threatening heat.
Yangsan, located in South Gyeongsang Province, reached 42.5°C [1]. This mark stands as the hottest temperature ever recorded in the country's history [1]. Other regions also saw extreme spikes, with Daegu reporting a maximum temperature of 41°C [3, 4].
In the capital, Seoul temperatures hovered around 37°C [3]. The intensity of the heat was evident earlier in the week; for example, Samcheok recorded a morning high of 34.6°C on Aug. 1 [6].
Some reports describe this period as the hottest day in 122 years [4]. While some forecasts for the weekend suggested peaks up to 39°C [5], actual readings in the southeast have already surpassed those estimates [1].
National weather authorities have warned that extreme heat will persist through the weekend of Aug. 2-4 [2, 5]. Residents are urged to follow emergency protocols as the heatwave continues to affect multiple provinces.
Scientists said the increasing frequency and intensity of such heatwaves are linked to the climate crisis driven by human activity [7].
“Yangsan hit 42.5°C, the highest temperature ever recorded in South Korea.”
The breach of a 122-year temperature record suggests that South Korea's baseline climate is shifting. The discrepancy between forecasted peaks of 39°C and the actual 42.5°C reading indicates that extreme weather events may be accelerating faster than current meteorological models can predict, increasing the risk of heat-related mortality and infrastructure strain.
