Ongoing heatwave conditions across the Seoul-Incheon region, with official nighttime heat advisories and persistent high humidity, support trader focus on minimum temperatures near 24–26°C for August 9. Short-range forecasts from the Korea Meteorological Administration indicate overnight lows around 25°C, reflecting limited radiative cooling under humid, partly cloudy skies and urban heat retention. Model consensus shows minor variations driven by expected wind speeds and cloud cover, which can shift the exact minimum by 1–2°C. Historical August baselines near 22–24°C underscore how current atmospheric patterns sustain warmer nights, keeping the closely matched 24°C, 25°C, and 26°C outcomes as primary resolution candidates ahead of updated model runs.
