Korea Meteorological Administration (KMA) observations confirm Seoul's morning minimum temperature—the lowest between 3 a.m. and 9 a.m.—reached exactly 9°C on April 22, under clear skies and light winds that enabled typical radiative cooling overnight. This aligns with the latest short-term forecast updates from KMA, reflecting stable high-pressure conditions over the Korean Peninsula and consensus from global models like ECMWF and GFS, which projected lows in the 8–10°C range based on recent soundings and surface data. Trader consensus at 100% implied probability underscores this evidence-based certainty, with historical April morning lows in Seoul averaging 6–9°C providing climatological support. Realistic challenges would require a rare data revision from KMA stations or unforecasted cold air intrusion, both improbable at this stage as daytime warming has commenced. Final KMA summary expected later today.
