Recent forecasts from the Korea Meteorological Administration and global models indicate a daily high of 27–28°C in Busan on September 7, driven by northeasterly winds and partly cloudy conditions under stable high pressure that limit daytime heating. Sea surface temperatures near seasonal norms and the absence of southerly flow or clear skies reduce the likelihood of exceeding 29°C, though model spreads allow for modest upward revisions. Trader emphasis on 29°C reflects uncertainty in final model runs and historical September variability, with new KMA updates and ensemble outputs expected within 48 hours likely to refine these implied probabilities.
