Recent KMA and international model consensus points to a daytime high of 25–26°C in Seoul and Incheon on October 11 under partly cloudy skies, light northerly winds, and continued above-average autumn warmth with no strong frontal systems. This setup, following several days of unseasonable late-summer heat, has concentrated trader sentiment on 26°C as the most probable peak while allowing 25°C as a close alternative if afternoon cloud cover or minor cooling develops faster than expected. Official station observations from the Korea Meteorological Administration will determine the exact maximum, with limited precipitation risk keeping extremes outside the leading outcomes unlikely.
