South Korea experienced its hottest day in modern history on Sunday, as temperatures climbed to 42.5C (108.5F). According to the Korea Meteorological Administration, this marks the highest temperature recorded in the country since modern weather observations on the Korean Peninsula began in 1904.

The historic peak occurred in the southeastern city of Yangsan, located approximately 310 kilometres (192 miles) southeast of Seoul. The region has faced extreme conditions for several days, with Yangsan recording temperatures exceeding 40C (104F) for five consecutive days. Officials have expressed concern that the heat could potentially climb even higher, reaching 43C (109.4F).

Nearby areas have also been significantly impacted. In Gyeongju, situated about 240 kilometres (151 miles) southeast of Seoul, the mercury reached 40.2C (104.4F), marking the first time this year that the city has surpassed the 40C threshold.

In response to the extreme weather, the government has activated a Level 2 emergency operation of the disaster response headquarters to coordinate a nationwide effort. Prime Minister Han Seong-sook has issued emergency directives requiring government ministries and provincial authorities to bolster safety measures for vulnerable populations. Furthermore, officials have been instructed to ensure the stability of the nation's power and water supplies during the heatwave.
