Trader sentiment clusters tightly around 10–12°C for Seoul's March 21 high temperature, driven by the Korean Meteorological Administration's (KMA) latest forecast pinpointing 11°C amid ensemble models from ECMWF and GFS averaging 10.5–11.5°C. A weakening Siberian high-pressure ridge allows mild southerly flows, but an incoming low-pressure trough introduces uncertainty, with 20–25% model spread potentially pushing outcomes to 9°C (cooler northerlies) or 13°C (delayed front). Historical March 21 highs average 11.8°C, yet urban heat island effects in Seoul amplify readings by 1–2°C; traders weigh hourly updates as diurnal peaks near 2–4 PM KST differentiate the razor-thin odds.
