Trader consensus on Polymarket favors a Seoul high temperature of 17°C (22%) or 16°C (21%) on March 28, propelled by the Korea Meteorological Administration's latest forecast indicating a daytime peak near 17°C under mild southerly flow and partial cloud cover. Differentiating these close outcomes, ECMWF ensemble models average 16.5°C with a tight spread (±1.5°C), while GFS runs skew slightly warmer at 17-18°C due to stronger ridging over the Korean Peninsula; historical March 28 averages hover at 12-14°C, but this year's amplified jet stream variability adds uncertainty. Traders eye tomorrow's 12Z model updates for resolution-defining shifts in boundary layer mixing and frontal timing.
