Recent forecast model runs from sources including the Korea Meteorological Administration and international ensembles indicate a highest temperature in the Incheon/Seoul area on October 16 most likely between 22–23°C under mostly cloudy skies with light winds and possible patchy drizzle. This narrow range reflects modest model spread on daytime heating amid a migratory high-pressure influence, following several days of above-average warmth. Light precipitation chances and variable cloud cover introduce minor uncertainty in maximum readings, while climatological norms for mid-October hover near 20°C. Updated model guidance and official briefings expected overnight will likely refine the exact peak before market resolution.
