Most heat-wave and tropical-night warnings across South Korea have been lifted as morning temperatures dropped this Wednesday [1].
This shift marks a transition from extreme summer heat, though coastal regions remain under threat from lingering typhoon influences and potential flooding.
In Seoul, the morning temperature was between 21.3 °C and 21.5 °C [1, 2], which is below the historical average for this time of year [1]. A YTN weather reporter said the air felt cooler for the morning commute than the previous day.
Despite the cool start, midday temperatures are expected to rise. Seoul is forecast to reach a high of 32 °C [1], returning to typical seasonal levels. Other cities reported morning temperatures of 20.7 °C in Jeonju, 22.7 °C in Busan, and 31 °C in Daegu [1].
While tropical-night warnings have been cancelled nationwide, heat-wave warnings remain active for some areas of Gyeonggi-do [1].
The east coast, including Gangneung and the Yeongdong area, faces a different set of challenges. Temperatures there were recorded at 25 °C [1]. This region is expected to experience strong winds and rain, creating a risk of low-land flooding due to the combination of high tides, and precipitation [1, 2].
Weather officials said the current patterns are driven by a seasonal transition that has eased the extreme heat in the interior, while coastal areas continue to deal with the remnants of typhoon activity [1].
“Heat-wave and tropical-night warnings have been lifted except for some areas of Gyeonggi-do.”
The lifting of nationwide heat warnings suggests a break in the extreme summer peak for the Korean peninsula. However, the shift in weather patterns is transferring the primary risk from heat-related health emergencies to coastal infrastructure threats, as high tides and wind-driven rain increase the likelihood of flooding in the east.
