Korea Meteorological Administration's latest medium-range forecast, issued March 30, projects a high of 20°C in Seoul on April 3 under partly cloudy skies with 30% precipitation probability, elevating trader consensus toward 19°C or higher at 21.5% while closely matching 16–18°C outcomes amid inherent spring forecast uncertainty. Ensemble models like GFS and ECMWF show variability in high-pressure ridge strength steering warmer air from the south, potentially tempered by northerly winds or isolated showers increasing cloud cover. Historical early-April highs average 16–17°C, but recent warming trends and low wind shear favor mild conditions; watch KMA short-term updates and new 12Z model runs for shifts as resolution nears.
