Recent official forecasts from the Korea Meteorological Administration and international models indicate a daytime maximum in Busan around 30–34 °C on August 12, with partly cloudy skies, light northeasterly winds, and minimal precipitation. This range reflects the ongoing influence of the North Pacific High, which maintains warm, humid southerly flow while increasing afternoon cloud cover that limits peak solar heating compared with clearer conditions earlier in the month. Coastal sea-breeze effects and the city’s maritime setting further moderate extremes, keeping the most probable outcomes clustered near 30–32 °C. Traders’ tight distribution across these bins therefore captures residual uncertainty in exact cloud timing and boundary-layer mixing rather than any broad shift in the synoptic pattern. Updated model runs and KMA briefings over the next 48 hours will likely narrow the implied probabilities as the event approaches.
