Trader sentiment on Seoul's highest temperature March 25 leans toward mild conditions, with 15°C or higher at 33.5% implied probability driven by recent ECMWF and GFS ensemble forecasts projecting above-normal warmth from a weakening Siberian High and southerly flow. Korea Meteorological Administration updates similarly indicate peaks around 14°C, though model spread introduces high uncertainty, spreading odds evenly across 11-15°C outcomes. Key variables include jet stream positioning—northward shifts favor 13-15°C, while late cold surges could drop to 10-12°C—and urban heat island effects amplifying station readings at official sites like Jongno. Historical March 25 highs average 12.5°C with 3-4°C variability, underscoring risks from volatile spring patterns as traders eye daily KMA revisions.
