Trader consensus clusters tightly around 14–16°C for Seoul's March 27 high temperature, driven by the Korean Meteorological Administration's (KMA) latest forecast pinning daytime peaks at 15°C under dominant high-pressure ridging, with ensemble models like ECMWF and GFS showing minimal spread of ±1°C. Differentiating factors include subtle cloud cover discrepancies—ECMWF drier for solar heating versus GFS' partial overcast risking cooler 14°C—and southerly winds advecting mild maritime air above March's 13°C climatological average. Urban heat island amplification in Seoul favors the 15°C edge (22.5% implied probability), though a pre-dawn cold pool could cap at 14°C (20.0%); watch KMA's evening update for resolution shifts.
