Recent forecasts from multiple models indicate a high near 24–25°C in the Seoul-Incheon area on September 28 under partly cloudy skies and moderate westerly flow. This positions 24°C as the leading outcome in trader consensus, with nearby values reflecting typical model spread and minor differences between urban Seoul and Incheon airport measurements. Light winds and limited daytime heating from cloud cover are suppressing peaks relative to the prior weekend’s warmer readings, consistent with the seasonal transition toward cooler autumn conditions. Updated model runs and official agency briefings in the next 24–48 hours will refine the exact maximum before resolution.
