Recent forecasts from regional models point to a late-July heat surge in Busan driven by a strong subtropical high and southerly advection of warm, moist air from the East China Sea, pushing daytime maxima toward 37–40 °C on July 31. Coastal sea breezes and marine-layer moderation typically cap extremes, yet weak winds, urban heat-island effects, and limited cloud cover could allow brief spikes above 38 °C. Historical July averages near 29–30 °C underscore the anomaly, while ensemble spread and possible afternoon convection introduce uncertainty between the tightly matched 37 °C, 38 °C, and 39 °C outcomes. Updated guidance from the Korea Meteorological Administration and next model runs will refine peak timing and any rainfall suppression ahead of resolution.
