Korea Meteorological Administration's short-range forecast, updated at 15:00 on May 9, projects a 24°C daytime high for Seoul on May 10 under clear skies, zero precipitation probability, and light southerly winds—driving trader consensus to 60% market-implied odds for 22°C or higher at the resolving Incheon International Airport station. This aligns with a warming trend from observed highs of 18°C on May 5, 19°C on May 7, and 20°C on May 9, reflecting a stabilizing high-pressure ridge enhancing solar heating amid early-May climatological averages near 22°C. Coastal Incheon models showing 21°C highlight microclimate variations and potential afternoon cloud development as key uncertainties; watch KMA's evening update and initial observations for shifts ahead of resolution.
