Recent Korea Meteorological Administration forecasts, shaped by persistent North Pacific High influence, position 31–33°C as the most probable highs for Busan on August 19, with traders assigning the strongest implied probability (39.5%) to exactly 32°C. Short-range models show mostly cloudy skies, a daytime maximum near 33°C, and overnight lows around 24°C, consistent with late-August climatology where sea breezes and humidity moderate peaks near the southeastern coast. Minor model spread around cloud cover and any passing showers accounts for the tight clustering between 31°C and 33°C, while probabilities fall sharply outside this range. Updated KMA briefings and regional ensemble runs over the next 48 hours remain the key catalysts likely to refine these market-implied odds.
