Current Korea Meteorological Administration forecasts project a daily minimum of 24°C for Incheon/Seoul on August 22 amid lingering summer humidity, mostly cloudy skies, and moderate rain chances that limit nocturnal radiative cooling. Trader consensus clusters tightly around 23–24°C because small variations in overnight cloud cover, wind speed, or precipitation timing can shift the low by 1°C in either direction. High humidity and weak pressure gradients reduce the potential for stronger cooling that would favor 22°C or below, while any clearing trend could push readings toward 25°C. Updated model runs and KMA briefings over the next 48 hours will clarify whether persistent cloudiness or brief breaks in the marine layer tip the balance.
