Korea Meteorological Administration observations confirm Seoul's daytime high temperature reached 12°C on April 11 amid an untimely cold snap, with northerly winds and persistent cloud cover capping insolation and suppressing readings well below the seasonal April average of 18°C. Hourly data shows peaks around midday at 12–14°C before cooling to 11°C by evening under mostly cloudy skies, aligning with model consensus from short-range forecasts that factored in a lingering cold air mass. Trader consensus at 99.9% implied probability reflects this observational lock-in, as sunset nears with minimal solar heating potential. Realistic challenges—sudden clearing or measurement revisions—are improbable given current atmospheric stability and diurnal cooling trends, though final KMA daily summary will confirm resolution.
