Latest ensemble forecasts from the Korea Meteorological Administration (KMA) and ECMWF models cluster Seoul's March 26 high temperature around 13-14°C, driving the razor-thin odds split between those outcomes at 25% and 24.5%. High-resolution guidance shows a 2°C spread stemming from uncertain mid-level cloud cover ahead of a weak frontal boundary, with light southerly winds potentially boosting peaks by 1°C via mild advection. Historical late-March data averages 12°C highs, but persistent positive temperature anomalies (+2°C monthly) from weakened East Asian winter monsoon favor the warmer side. Traders eye KMA's afternoon update for convective risks that could cap readings at 13°C versus clearer skies pushing 14°C+.
