Recent forecast model runs from agencies including the Korea Meteorological Administration and global ensembles show stable high pressure and light easterly flow over Busan on October 9, supporting daytime highs near 24–26 °C under partly cloudy skies. This autumnal pattern—typical for early October with solar angles yielding peak temperatures in the mid-20s °C—has kept the 26 °C outcome at the market-implied lead while capping upside risk from stronger warming. Minimal precipitation and moderate humidity further limit convective enhancement, though any late-day cloud increase or slight wind shift could trim the maximum by 1–2 °C. Updated model guidance expected within the next 24–48 hours will refine these probabilities ahead of the daily high resolution.
