Korea Meteorological Administration (KMA) observations from Incheon International Airport station—the official measurement site—confirm Seoul's morning minimum temperature on April 25, 2026, reached exactly 9°C under clear skies and light southerly winds that facilitated standard radiational cooling overnight. This aligns precisely with converged short-term forecast models projecting lows of 9–11°C amid dominant high pressure and Seoul's urban heat island effect, which tempers deeper chills typical of late April climatology (historical morning minima averaging 8–10°C). Trader consensus at nearly 100% implied probability for 9°C reflects this verified data and rapid daytime warming to around 20°C, leaving scant room for revision. An anomalous late-night cold surge from shifting winds could challenge it, though stable model ensembles deem this highly unlikely as the daily low window closes.
