Korea Meteorological Administration forecasts indicate a daytime high of 19°C for Seoul on May 8 under clear skies, with hourly data from Gimpo Airport showing peaks of 19°C midday before easing to 17°C by evening, driving trader consensus toward closely matched 17–20°C outcomes at over 85% implied probability. This positioning reflects recent model consensus from KMA, GFS, and ECMWF runs capturing mild spring conditions with a weak high-pressure ridge aloft limiting warming, following cooler-than-average early May trends amid neutral ENSO influences. Differentiating factors include potential afternoon cloudiness or southerly sea breezes, which could suppress peaks toward 17–18°C or allow slight intensification to 20°C; 12Z forecast updates on May 7 will clarify model spread as resolution nears. Climatological May 8 highs average 21°C, underscoring inherent short-range uncertainty in boundary-layer mixing and insolation.
