Recent model consensus from the Korea Meteorological Administration points to peak daytime heating near 36–37°C in Busan on August 2, driven by a strong North Pacific High promoting subsidence and warm advection across the Korean Peninsula. Coastal sea breezes typically moderate extremes, yet elevated sea-surface temperatures and high humidity from the summer monsoon pattern limit cooling and raise heat index values. Forecast uncertainty stems from possible afternoon cloud development or slight shifts in wind direction that could cap the maximum at 36°C or allow brief spikes toward 38°C. Historical August baselines average 30–32°C, so current conditions reflect amplified ridging rather than routine variability. Updated KMA guidance and local observations through the morning will refine the final recorded high before market resolution.
