South Korea is continuing to experience intense late-summer heat even after Cheoseo, the traditional seasonal marker associated with cooler weather. Heatwave alerts remain in place across most of the country, underscoring how little relief the seasonal transition has brought so far. Korean weather coverage has linked the persistence of the heat to the continued influence of the North Pacific high-pressure system.

For residents, the practical impact is straightforward: the risk of heat-related illness remains elevated, especially for older people, children and anyone working outdoors. High temperatures also keep cooling demand elevated and can make commuting, exercise and other routine activities more difficult during the hottest parts of the day. The continued alerts mean people should not assume that the arrival of late August has materially reduced heat risk.

The important question now is how quickly the atmospheric pattern changes. Until the dominant high-pressure system weakens, daytime temperatures are likely to remain uncomfortable in many areas. People should keep checking local advisories, limit prolonged exposure during peak heat and maintain hydration even if mornings or evenings begin to feel slightly more seasonal.
