Recent forecasts from the Korea Meteorological Administration indicate that the North Pacific High will continue directing warm, humid air toward the Korean Peninsula through mid-August, sustaining heatwave conditions into August 13. Busan’s coastal setting introduces moderating sea breezes that typically limit maxima below inland peaks, creating tight clustering around 31–33°C in ensemble models. Traders weigh these dynamics against potential short-term variability from steering patterns or minor precipitation, reflected in the closely matched leading outcomes. Updated KMA guidance and refined model runs expected in the next 48 hours will clarify intensification potential or any easing trend.
