The Korea Meteorological Administration has issued a severe heat wave warning for Seoul and the surrounding metropolitan area as temperatures are forecast to reach 39°C [1].
This extreme weather occurs during "Ipchu," the traditional seasonal marker for the start of autumn. The persistence of high temperatures despite this transition indicates a prolonged period of environmental stress for the region's urban population.
Forecasts indicate that daytime highs will reach 39°C [1] in Seoul, Goyang, and Jeonju [1]. Other areas, including Chuncheon, are expected to see temperatures hit 38°C [1]. The severe warning also extends to Yeongseo, Jeonju, Gwangju, and parts of the Honam region [2].
Residents have faced a relentless stretch of extreme heat. Seoul has experienced tropical nights, where temperatures remain high after sunset, for more than half a month [1]. At the time of the report, the temperature in Seoul was 28.7°C [1], while Jeju and Busan were above 27°C [3].
"Today is 'Ipchu,' the solar term that signals the start of autumn, but I bring news that it is inevitably hot," a YTN weather reporter said [3].
While the interior and western regions battle heat, the weather pattern is expected to shift for other coastal areas. Forecasts indicate rain is expected on the east coast and Jeju over the coming weekend [1].
"A 'severe heat wave warning' has been issued for the metropolitan area including Seoul, Yeongseo, Jeonju, Gwangju, and some areas of Honam," the reporter said [2].
“Temperatures are forecast to reach 39°C in Seoul, Goyang, and Jeonju.”
The issuance of a 'severe' warning during Ipchu highlights a disconnect between traditional seasonal calendars and current climatic realities in South Korea. The combination of record-high daytime temperatures and a 15-day streak of tropical nights suggests an intensified urban heat island effect in Seoul, which may increase the risk of heat-related illnesses and place significant strain on the national power grid.
