The Polymarket trader consensus assigns a 100% implied probability to a highest temperature of 13°C in Seoul on March 27, driven by the Korea Meteorological Administration's (KMA) latest forecast pinpointing a daytime maximum of exactly 13°C amid partly cloudy conditions and light northerly winds limiting warm air advection. Ensemble model guidance from ECMWF and GFS corroborates this, with tight uncertainty bands (±1°C) reflecting stable upper-air patterns and no diurnal heating spikes expected. Current observations show morning lows near 8°C rising steadily but capped by cloud cover. Scenarios challenging this—such as sudden solar clearing or a wind shift—remain improbable given March climatology, where Seoul averages 11-12°C highs; resolution hinges on KMA's official hourly data release post-midnight.
