Korea Meteorological Administration short-term forecasts project Seoul's highest temperature on April 19 reaching 24–29°C at Incheon International Airport station—the market's resolution point—driving the 100% implied probability for 24°C or higher amid an unseasonable mid-April heatwave. Recent observations show daytime highs already surpassing 27°C earlier this week, fueled by persistent high-pressure systems and above-normal solar insolation, well exceeding the seasonal average of 17°C. Global models like ECMWF and GFS align on continued warmth with light winds and minimal cloud cover. While sudden cold fronts or increased cloudiness could cap peaks below 24°C, current trajectories and hourly KMA updates indicate negligible risk, reflecting trader consensus on robust scientific evidence.
