Seoul is under a heat-wave warning as temperatures approach extreme tropical-night levels during the morning commute [1].
This weather event threatens public health and infrastructure across South Korea, as intensifying summer heat prevents nighttime cooling and increases the risk of heat-related illnesses.
According to YTN News, the temperature in Seoul was 26.2 °C, with a perceived temperature nearing 30 °C [1]. This level of heat aligns with the threshold for "extremely hot nights," known as cho-yeoldaya [1].
Officials have issued heat-wave and tropical-night advisories for most of the country [1]. In Seoul, the heat-wave warning remains in effect, with perceived temperatures expected to reach 36 °C during the day [1].
Regional forecasts indicate even higher peaks outside the capital. Daytime highs are expected to reach 34 °C in Seoul, 37 °C in Daegu, and 39 °C in Yangsan [1].
In Gyeongsang-nam-do, severe heat-wave warnings have been lifted for most areas, except for Yangsan, Uiryeong, and Changnyeong [1].
"The current temperature in Seoul is 26.2 degrees, and the perceived temperature is approaching 30 degrees, the standard for an extremely hot night," YTN News said [1].
Residents are advised to remain cautious as the Korea Meteorological Administration continues to monitor the intensifying summer heat wave [1].
“Seoul is under a heat-wave warning as temperatures approach extreme tropical-night levels.”
The prevalence of 'cho-yeoldaya' or extremely hot nights indicates a failure of the urban environment to cool down overnight, which exacerbates the physiological stress on the human body. When combined with daytime highs nearing 40 °C in southern regions, this creates a compounding heat effect that increases the burden on the national power grid and public health systems.
