Recent numerical weather prediction runs from the Korea Meteorological Administration and ensemble guidance indicate a daily maximum in Busan on August 21 likely centered near 30–32 °C, driven by residual subtropical high pressure, moderate southerly flow, and urban heat retention amid partly cloudy to overcast skies. Typhoon Saudel’s northwestward track is introducing increased moisture and potential showers that could suppress afternoon heating, while model spread arises from variable timing of cloud cover and precipitation. These conditions align with climatological August averages of 29–31 °C yet allow for brief clears that support the market’s concentration around 32 °C, with lower odds for 33 °C or above reflecting limited intensification potential before any frontal or tropical influences arrive. Updated model cycles and official KMA briefings over the next 48 hours will refine land-sea breeze and insolation effects critical to exact peak readings.
