Korea Meteorological Administration observations and METAR reports from Incheon International Airport Station—the market's resolution source—confirm Seoul's highest temperature reached 12°C around midday on April 11, 2026, amid persistent haze, mostly cloudy skies, and cool northerly winds that capped daytime heating despite early model forecasts implying 15–17°C potential. High humidity near 90% further muted solar insolation, aligning with historical early-April patterns where cloud cover often shaves 2–4°C off climatological highs of 16–18°C. With nighttime lows now at 4°C and no further warming possible before midnight KST resolution, trader consensus at 100% reflects finalized Wunderground daily history data; only a rare post hoc measurement revision could challenge this, though KMA protocols rarely alter settled peaks.
