Recent meteorological conditions over the Korean Peninsula feature a transition from the early-August heatwave peak (with Seoul-area maxima near 39–40°C) into a more active monsoon-influenced pattern, with increased cloud cover, scattered precipitation, and moderating temperatures expected through mid-month. Official Korea Meteorological Administration guidance for 16 August projects a daytime maximum near 30°C in the Seoul-Incheon region amid 60% rain probability, while ensemble guidance from global models shows modest spread tied to the exact timing, duration, and intensity of showers plus boundary-layer moisture. These variables primarily differentiate the closely matched 27–29°C outcomes: earlier or heavier rainfall and thicker stratiform cloud decks would limit insolation and cap the maximum closer to 27°C, whereas delayed or lighter precipitation and partial clearing would allow greater surface heating and push readings toward 29°C. Sea-breeze effects from the Yellow Sea and urban heat-island contributions at Incheon further modulate the precise peak, but current observational trends and model consensus keep the distribution centered on 28°C with limited probability mass beyond 30°C or below 27°C.
