**Trader sentiment for the highest temperature in Busan on August 31 centers on 31–33°C, with 32°C holding the strongest implied probability at 50%.** Official Korea Meteorological Administration guidance forecasts a daytime high of 32–34°C under generally cloudy skies with periods of rain totaling 30–80 mm, driven by a stationary front interacting with moist southwesterly flow. Cloud cover, widespread precipitation, and evaporative cooling from earlier heavy rains across the southern peninsula are expected to cap daytime heating, keeping temperatures near the lower end of the seasonal range rather than allowing stronger insolation under clearer skies. Recent model consensus and KMA updates have reinforced this moderate outcome, with southwest winds around 5–8 mph and high humidity (70–85%) further limiting peak values. Forecasts from international sources show some spread (roughly 28–31°C in some runs), but the official outlook and recent precipitation patterns anchor market pricing toward 32°C as the most likely resolution. New KMA updates or model runs tomorrow morning remain the key near-term catalysts.
