Recent forecasts from multiple models indicate a high around 28–30°C for Busan on September 14 under mostly clear to partly cloudy skies with light winds and minimal rain chances, consistent with stable high-pressure conditions typical of early autumn in the region. Model consensus clusters near 29°C, though slight variations in afternoon sea-breeze strength or cloud cover could push readings toward 30–31°C, explaining why traders assign the highest implied probabilities (30.5% for 31°C, 26% for 30°C) to those outcomes. With probabilities closely bunched, differentiation hinges on precise timing of peak heating and local measurement protocols at official stations, where even small shifts in solar insolation or urban heat retention matter. Updated model runs and Korean Meteorological Administration guidance over the next 48 hours represent the key catalysts likely to refine these market-implied odds.
