Trader consensus on Polymarket reflects tight uncertainty in forecast models for Seoul's highest temperature on April 4, with 15°C (25.5% implied probability) edging out 16°C (23.5%) and 17°C or higher (20.5%), driven by the Korea Meteorological Administration's (KMA) latest short-range guidance projecting morning rain tapering to partly cloudy conditions amid a passing frontal system. Today's southerly winds pushed highs near 20°C under mostly cloudy skies, but incoming precipitation and persistent cloud cover are expected to cap daytime heating, with model ensembles like GFS and ECMWF diverging by 2–3°C on peak warmth based on clearing timing. Historical early-April highs average 15–17°C at Incheon International Airport station, the market's resolution point; evening KMA updates and hourly observations will refine trader positioning before tomorrow's outcome.
