Recent forecasts from the Korea Meteorological Administration and international models indicate clearing conditions after widespread thunderstorms on August 21–22, positioning a partly cloudy day with light westerly winds for August 23 that favors peak temperatures near 30–32 °C at Incheon. The North Pacific high-pressure ridge is strengthening, promoting subsidence and reduced cloud cover while residual moisture from the East Asian monsoon keeps humidity elevated and supports apparent temperatures several degrees above the dry-bulb reading. Historical August climatology for the Seoul metropolitan area shows mean daily maxima of 29–30 °C, so the current setup represents a modest positive anomaly driven by post-frontal clearing rather than an extreme heat dome. Ensemble guidance shows limited spread, with the majority of runs clustering in the 30–32 °C range and only isolated higher solutions reaching 33–34 °C if insolation exceeds expectations. Updated model runs and official briefings over the next 48 hours will refine the precise maximum before market resolution.
