Recent forecast models from sources like the Korea Meteorological Administration indicate Busan will experience mostly clear to sunny conditions on October 5 under a stable high-pressure system, with daytime highs projected near 24–25°C amid moderate northwest winds and low humidity. This aligns with early-autumn climatology, where average October maxima hover around 22–23°C, positioning the 24°C and 25°C outcomes as market leaders due to tight model consensus and minimal precipitation risk. Ensemble spreads introduce modest uncertainty around local urban heating or slight timing shifts in peak insolation, supporting elevated implied probabilities for the mid-20s range while keeping extreme outliers like 29°C or higher as lower-probability scenarios pending any last-minute warming signals. Official observations will resolve the market on October 6.
