Korea Meteorological Administration (KMA) observations and Incheon International Airport METAR reports confirm Seoul's highest temperature on April 11 reached exactly 12°C, peaking at 12.2°C around 3:30 PM KST amid persistent cloud cover, mist, and northerly winds that limited solar insolation and daytime heating. Short-term KMA forecasts accurately anticipated this cap at 12–14°C, reflecting a cool air mass following early April's variable spring patterns, well below the mid-April climatological average of 17–18°C. Trader consensus at 100% implied probability reflects this locked-in observational data from official surface stations, with resolution imminent via KMA daily records. Realistic challenges are minimal but could include a rare post hoc revision from overlooked hourly peaks at peripheral sensors; watch final KMA summary for confirmation.
