Latest forecast models, including GFS and regional guidance, indicate a daytime high of 20–21°C for Incheon on October 15 under partly cloudy skies with southwesterly winds of 15–25 km/h. This autumnal pattern, featuring mild advection without strong frontal systems or clear-sky radiative heating, supports the market's strong 60% implied probability for 21°C. Historical October averages near 20°C provide additional context, while minor model spread around potential cloud cover or showers accounts for secondary weighting on 20°C and 22°C. Official Incheon station observations will determine resolution once the day concludes.
