Trader consensus on Polymarket closely splits between a 14°C high (24.5%) and 13°C (23%) for Seoul on March 27, mirroring ensemble forecast guidance from ECMWF and GFS models centering daytime peaks in that narrow 13–14°C range amid a developing high-pressure ridge over East Asia. This setup promises mild southerly flow displacing recent cooler air masses, pushing above the late-March climatological average of ~12°C based on 30-year Korea Meteorological Administration data. Key differentiators include timing of transient frontal boundaries and jet stream undulations, with 2–3°C model spreads reflecting inherent daily forecast uncertainty; KMA high-resolution updates and new ensemble runs due in the next 24–48 hours could sharpen or shift probabilities.
