Official forecasts from the Korea Meteorological Administration point to a daytime maximum near 31°C in the Seoul-Incheon area on August 23 under cloudy skies and a 30% chance of showers, keeping trader consensus tightly clustered around 30–32°C. Differentiation among these outcomes hinges on variables such as the precise timing and coverage of any convective showers, which could suppress peak heating by 1–2°C, versus periods of partial clearing that allow greater insolation and push readings toward 32°C. Late-summer climatology, with average highs near 30°C and high humidity, combined with urban heat-island effects and potential steering by regional pressure gradients, sustains this narrow range. Updated model runs and hourly observations through the morning of the 23rd will refine the exact maximum before market resolution.
