The Seoul city government issued its first heat advisory of the year on Thursday, warning of midsummer-like temperatures across the capital [1, 2].
This early onset of extreme heat poses significant public health risks, particularly for large crowds gathering in outdoor public spaces during the current sporting season.
The advisory took effect at 2 p.m. on the 18th [2]. The warning covers several areas of the city, including the southwestern districts and southeastern districts such as Gangdong, Songpa, Gangnam, and Seocho [2].
Officials said temperatures are expected to rise above 30 °C [1]. This advisory arrives 12 days earlier than the first heat advisory issued last year [2].
City representatives said the public should stay hydrated and take necessary precautions against heat-related illness. They specifically highlighted the need for caution among those attending World Cup fan-parks [1, 2].
Forecasters said the heat is expected to continue on the 19th, though the weather may include possible showers [1, 2].
“Seoul issued its first heat advisory of the year 12 days earlier than last year.”
The acceleration of the heatwave timeline in Seoul suggests a shift in seasonal weather patterns. By issuing an advisory nearly two weeks earlier than the previous year, the city is bracing for a longer or more intense summer, which complicates urban heat management and public safety for high-density events.
