Korea Meteorological Administration's latest numerical weather prediction models forecast a precise high temperature of 9°C in Seoul on March 26, driven by persistent cold air advection from a continental high-pressure system and northerly winds suppressing daytime warming. This aligns with ensemble model consensus from ECMWF and GFS runs, showing minimal deviation across members, reflecting stable synoptic patterns observed in recent 24-48 hour updates. Historical March averages hover around 11°C, but current conditions mirror chilly analogs from prior cold snaps. Trader consensus at 99.9% implied probability underscores this evidence-based outlook; realistic challenges include unforeseen low-level jet strengthening or increased solar insolation from clearing skies, potentially nudging temps toward 10°C, with final observations resolving the market.
