Recent model consensus from the Korea Meteorological Administration and global ensembles indicates a highest temperature near 32°C in Busan on August 21, driven by typical late-summer subtropical high pressure, sea-surface temperatures around 28–29°C fueling humidity, and variable afternoon cloud cover with isolated showers that limit full solar heating. The closely matched 32°C and 33°C probabilities reflect uncertainty in exact peak timing and convective activity, as even modest increases in insolation or shifts in steering flow could push readings higher while stronger moisture convergence would cap them lower. Historical August maxima average 30–31°C, providing context for why traders assign minimal weight to extremes above 34°C at this lead time. Updated short-range forecasts expected within 48 hours will likely refine these odds ahead of resolution.
