Recent forecasts from the Korea Meteorological Administration and global models indicate Busan maximum temperatures on August 18 will likely reach 29–31°C under typical late-summer monsoon conditions, with scattered showers and high humidity moderating peaks. Sea surface temperatures in the Korea Strait and regional pressure patterns favor this range rather than extremes, consistent with historical August averages near 30°C. The market’s emphasis on 30–31°C outcomes aligns with current ensemble guidance showing limited intensification potential before resolution, though late model updates on steering flow or localized convection could shift the final reading within the two-day window.
