The Korea Meteorological Administration's latest forecast pins Seoul's highest temperature on March 26 at around 9°C under cloudy skies and northerly winds ushering in cooler air from Siberia, driving trader consensus to 75% implied probability for exactly 9°C. Updated model runs from the past 24 hours, including ECMWF and GFS ensembles, show convergence on subdued warming potential after earlier runs hinted at 10-11°C amid recent mild spells averaging 12°C highs over the prior week. Historical March norms hover near 10°C, but current pressure patterns and cloud cover suppress daytime heating, with minimal upside risk above 10°C barring unexpected clearing. Official observations resolve the market post-midnight March 27 KST, as traders weigh inherent short-range forecast uncertainty.
