Trader consensus on Polymarket favors a Seoul high of 12°C at 38% implied probability for March 21, closely trailed by 11°C (32.5%) and 10°C (20.5%), reflecting tight clustering in ensemble weather models amid spring's variable synoptic patterns. The Korea Meteorological Administration's latest forecast points to a daytime peak near 12°C under weak high-pressure ridging and southerly flows, boosting odds for the warmer outcome, while ECMWF ensembles hint at 12-13°C potential from urban heat amplification. Cooler GFS projections around 10-11°C account for lingering northerly gusts post-cold front, differentiating the leaders; historical March 21 averages hover at 11.5°C with standard deviations under 2°C, underscoring low but pivotal model spread as the key uncertainty.
