Latest KMA short-range guidance for Busan on August 15 points to a daytime maximum near 32°C under mostly cloudy skies and a 30% chance of showers, establishing the current market concentration around 31–32°C. Coastal sea breezes and relatively high humidity moderate peak values, while the position of the North Pacific high and any weak frontal passages introduce ensemble spread across global models. Key variables include the exact timing and coverage of afternoon convection, which can shave 1–2°C off the high, versus clearer intervals that allow greater insolation and push readings toward 33°C or above. Historical August maxima in Busan average near 30–31°C, providing a climatological baseline against which the current warm, moist airmass is evaluated. Updated model runs and official KMA briefings over the next 48 hours will refine the distribution.
