South Korea is experiencing a severe heat wave with temperatures exceeding 41 °C in several southern regions this week [1, 2].
The extreme surge represents a dangerous shift in regional weather patterns, threatening public health and infrastructure as the heat spreads toward the Seoul metropolitan area [1, 2].
In Gyeongsangnam-do province, the city of Yangsan recorded a maximum temperature of 41.6 °C [1]. This mark broke the previous all-time national observation record [1]. Yangsan has now seen temperatures exceed 41 °C for two consecutive days [1].
Other cities in the region are also facing unprecedented conditions. For the first time, Gimhae and Changwon have recorded temperatures over 40 °C [1].
Meteorologists attribute the crisis to a combination of factors. A "dry monsoon" with very little rainfall has left the land parched, while the basin topography of the affected regions traps heat. Additionally, a double high-pressure system over the Korean Peninsula is driving hot winds over the mountains [1, 2].
"Yangsan rose to 41.6 degrees, again breaking the all-time highest temperature since national observations began," Jung Hye-yoon said [1].
The heat is not confined to the south. The Seoul metropolitan area is also being engulfed by the surge [1, 2]. A YTN news anchor said the Korean Peninsula is being swept by continuous, record-breaking heat waves [1].

The intersection of a double high-pressure system and basin geography creates a 'heat trap' effect that amplifies temperature spikes. When combined with a dry monsoon—where the typical cooling effect of seasonal rain is absent—the result is a record-breaking heat surge that exceeds the historical adaptive capacity of the region's urban infrastructure.
