Korea Meteorological Administration (KMA) observations from Seoul's official station (No. 108) confirm the highest temperature on April 28, 2026, peaked at 15°C amid mostly cloudy skies and light precipitation, driving trader consensus to 100% implied probability for this outcome. This marks a sharp departure from mid-April heat records exceeding 29°C, as a cold air mass and northerly flows suppressed daytime warming below seasonal norms of 18–20°C. Model forecasts from KMA had anticipated subdued highs due to persistent cloud cover and frontal activity, with minimal solar insolation limiting surface heating. Realistic challenges are negligible post-observation, barring rare data revisions from instrument recalibration or quality control audits, as daily maxima are finalized from hourly automated synoptic readings.
