Recent official forecasts from the Korea Meteorological Administration and international models indicate a maximum temperature in Busan around 29–33°C for August 21, with cloud cover, scattered showers, and possible thunderstorms expected to moderate peaks through reduced solar insolation and evaporative cooling. Coastal sea breezes along the southeastern Korean Peninsula further temper daytime highs relative to inland areas, while the position of the North Pacific High influences southerly moisture flow and humidity levels. Ensemble spread in precipitation timing and intensity creates the tight clustering around 31–33°C in trader pricing, as stronger or earlier rainfall would suppress readings toward 30°C or below, whereas partial clearing could allow brief warming to 34°C. Updated model runs closer to the date will likely refine these outcomes.
