Trader consensus on Polymarket prices a tight race among 18–20°C outcomes for Seoul's highest temperature on April 13, reflecting uncertainty in global forecast models like ECMWF and GFS ensembles, which show a 18–22°C spread amid variable cloud cover and light winds. Recent Korea Meteorological Administration (KMA) guidance notes April 12 highs near 16°C under mostly cloudy skies and easterly breezes, with temperatures running 2–3°C below prior estimates due to persistent cool air masses overriding spring warming trends. Mid-April climatology favors highs around 17–19°C, but afternoon cloud breaks or southerly flow could push toward 20°C, while overcast conditions cap at 18°C. Watch KMA's final short-term update today for refined guidance ahead of resolution via official station data.
