Trader consensus on Polymarket reflects high uncertainty in ensemble forecasts from the Korea Meteorological Administration (KMA) and global models like ECMWF and GFS, projecting Seoul's highest temperature on April 4 clustered tightly around 11–13°C with spreads of ±2°C. Differentiating factors include variable cloud cover—potentially 40% precipitation chance limiting solar insolation and capping highs at 11°C versus clearer skies pushing toward 13°C—alongside lingering northerly winds from recent cool spring patterns and urban heat island effects adding 1–2°C. Historical early-April averages hover near 13°C during cherry blossom onset under ENSO-neutral conditions, but model disagreements on frontal timing keep outcomes like 12°C (22.5% implied probability) narrowly ahead. Watch KMA daily updates and fresh ensembles for shifts ahead of resolution using official station data.
