Nighttime heat in Seoul has eased, leading officials to lift the tropical-night warning for the city [1, 2].
The shift provides critical relief for millions of residents who have endured a period of extreme heat. Lower nighttime temperatures reduce the physiological stress on the human body, which requires cooler periods to recover from daytime heat exposure.
Reporting from Banpo Hangang Park, weather caster Won Chae-young said the temperature in Seoul was approximately 29 °C as of 10 p.m. [1]. This represents a noticeable decline in the intensity of the heat wave that had previously gripped the region.
Thermal imaging data highlights the cooling trend. Won said that at the same time last Friday, ground temperatures were around 40 °C [1]. Current measurements show ground temperatures have fallen to approximately 35 °C [1], a difference of about five degrees.
Forecasts suggest this cooling trend will continue into Tuesday morning. The temperature in Seoul is expected to reach 24 °C [1]. Other major cities are seeing similar declines, with Daejeon forecasted at 23 °C and Gangneung at 21 °C [1].
An anchor for YTN said the nighttime heat in Seoul is slowing down as the extreme heat wave loses its strength [1]. The lifting of the warning indicates that the atmospheric conditions maintaining the tropical nights, where temperatures remain high throughout the evening, have finally shifted.
“Seoul temperature was approximately 29 °C as of 10 p.m.”
The lifting of the tropical-night warning suggests a break in the high-pressure systems that typically trap heat over the Korean Peninsula during summer. While daytime temperatures may remain warm, the drop in nighttime ground and air temperatures reduces the risk of heat-related illnesses and lowers the energy demand for overnight cooling in a densely populated urban center.
