**Clear skies and stable high pressure over the Korean Peninsula are positioning a daytime maximum near 22°C as the dominant outcome for Seoul and Incheon on October 7.** Official Korea Meteorological Administration guidance and multiple model runs project highs of 22–24°C under sunny conditions with light northwesterly flow, following overnight lows in the low teens that allow strong daytime heating without significant moisture or cloud cover. This aligns with typical early-October climatology for the region, where radiative cooling overnight contrasts with modest solar warming by afternoon. Traders appear to weight the tight clustering of forecasts around 22°C most heavily, with limited dispersion across ensembles keeping probabilities for 23°C or higher modest and those for 21°C or below as secondary scenarios if actual peak timing or station readings vary slightly. Updated model runs and KMA briefings through the evening of October 6 will provide the final inputs before resolution.
