Recent short-range forecasts from the Korea Meteorological Administration and ensemble models point to a daily maximum of 30–32°C in Busan on August 12, driving the market's heavy weighting toward those outcomes. Coastal sea breezes and the persistent North Pacific High are moderating peak heating under partly cloudy skies and low precipitation chances, aligning with typical mid-August climatology where average highs reach 29–31°C amid elevated humidity. This follows an early-August heatwave that pushed some regional readings above 40°C before conditions eased, leaving traders to price in the stabilizing influence of marine air and limited solar enhancement. Updated model runs and official briefings in the next 24 hours remain the key variables that could shift implied probabilities before resolution.
