South Korea has issued nationwide heat warnings after temperatures climbed to 34°C in Seoul and 36°C in Pohang [1].
The extreme heat puts a significant portion of the population at risk of heat-related illness, forcing the meteorological agency to expand emergency advisories across most of the country.
Weather caster Lee Hye-min of YTN said the conditions from the Ttukseom Han River swimming pool, where citizens have sought relief from the rising heat [2]. According to Lee, the perceived temperature in Seoul has already reached 32°C [2].
The meteorological agency expanded the heat warning at 10 a.m. local time [2]. A heat advisory now covers nearly the entire country, excluding some mountainous regions [2]. More severe heat alerts are currently active in southern Gyeonggi, western Jeollabuk, and parts of the Yeongnam region [2].
Meteorologists attribute the current weather pattern to a high-pressure ridge situated over the Korean Peninsula. This system is driving unusually hot and humid conditions, creating a "steaming" effect across urban centers [1, 2].
Local authorities are monitoring the situation as the weekend progresses. The combination of high humidity and peak temperatures increases the risk of heatstroke, particularly in the regions under the highest alert levels [2].

The presence of a high-pressure ridge suggests a stagnant weather pattern that can trap heat and humidity over the peninsula for extended periods. When heat advisories scale up to nationwide alerts, it typically signals a systemic stress on public infrastructure, including power grids and public health services, as the population relies more heavily on cooling systems.
