Recent model consensus from the Korea Meteorological Administration and global ensembles indicates daytime highs in Busan on July 9 will likely peak near 30°C, supporting the market's leading 34.5% implied probability on that outcome. Typhoon BAVI's projected track is introducing increased cloud cover, humidity, and potential light precipitation that could moderate peak temperatures through reduced solar heating and enhanced sea breezes along the Korea Strait coast. Historical July baselines for Busan cluster between 27–30°C, but subtle differences in BAVI's timing, intensity, or steering flow may determine whether readings reach 31°C or stay at 29°C, creating the tight spread across adjacent bins. Updated short-range runs and official advisories over the next 48 hours will refine these variables ahead of market resolution.
