Korea Meteorological Administration (KMA) observations confirm the highest temperature in Seoul reached exactly 22°C on April 23, 2026, at the official station, driving trader consensus to a near-certain 100% implied probability for this outcome amid mostly cloudy skies and moderate southerly winds that capped daytime heating. Morning readings hovered around 18°C by mid-morning, peaking modestly in the afternoon before cooling rapidly, aligning with forecast model consensus from short-range guidance that anticipated 22–23°C under persistent cloud cover and a stable high-pressure ridge. Scenarios challenging this—such as an unexpected clearing allowing solar heating to push beyond 23°C—were ruled out as the day progressed without significant insolation spikes, with final observations solidifying resolution criteria met for 22°C. KMA data releases typically finalize daily maxima post-midnight, minimizing revision risk.
