Korea Meteorological Administration (KMA) observations from Seoul's official weather station (No. 108) confirm the day's highest temperature reached exactly 12°C, driving trader consensus to 100% implied probability as the market nears resolution. Mid-afternoon peaks aligned with hourly data amid cool northerly winds, partial cloud cover, and limited insolation typical of late March climatology, where average highs hover around 12–14°C. Preceding forecast models from KMA and global ensembles accurately anticipated this under a stable high-pressure ridge. Realistic challenges would involve rare data corrections for sensor anomalies or disputes over measurement timing (daily max from midnight to midnight local standard time), but standardized protocols make revisions unlikely. Final KMA summary expected shortly after midnight.
