Recent model consensus from sources such as GFS indicates clear skies and northerly winds over Busan on October 2, supporting overnight radiative cooling after daytime highs near 24°C. This setup favors a minimum around 15–17°C, yet market-implied odds place 18°C or higher slightly ahead at 49% while 13°C sits near 42%, reflecting uncertainty in exact wind speeds, humidity levels, and any late cloud development that could limit cooling. Historical October averages for Busan show nighttime lows near 16°C, providing context for the tight clustering of probabilities across the 9–17°C range. Updated forecasts from the Korea Meteorological Administration ahead of the overnight period will likely refine these trader assessments.
