Yangsan, South Korea, recorded a daytime high of 41.6 °C this week, the highest temperature ever measured in the country [1].

This record-breaking heat signals an intensifying climate trend in East Asia, where extreme temperatures are increasingly challenging urban infrastructure and public health systems.

The temperature in Yangsan, located in Gyeongsangnam-do, surpassed the previous national all-time high by 0.2 °C [1]. This new peak followed a reading of 41.4 °C recorded the previous day [2].

According to reports, Yangsan is the first location in South Korea to exceed 41 °C on two successive days since official records began [1]. This surge is part of a severe heat wave that pushed temperatures above 40 °C for four consecutive days [1].

South Korea has maintained official temperature records for 122 years, dating back to 1904 [2]. The current heat wave has left residents struggling to cope with the intensity of the sun.

Choi Jae-sung, a resident of the area, said that without a fan, sweat continues to flow because it is so hot. He said that because of the heat, people are staying inside with air conditioners and fans running constantly [1].

Reporter Lee Sang-gon of YTN said that the daytime high in Yangsan broke the record for the hottest weather since meteorological observations began in the country, doing so in just one day [1].

“Yangsan is the first location in South Korea to exceed 41 °C on two successive days since records began”

The occurrence of two consecutive days above 41 °C in a single location is an unprecedented meteorological event for South Korea. By breaking a 122-year record within a 24-hour window, the region demonstrates a volatile temperature trajectory that may necessitate updated urban cooling strategies and emergency health protocols to prevent heat-related mortality.
