Recent forecasts from multiple models indicate a high of 24–26°C for Busan on October 5, driven by clearing skies, northwest winds at 8–11 mph, and minimal cloud cover that will allow strong daytime heating. This aligns with early October climatology, where average highs reach 22–23°C, though a brief warm anomaly has pushed trader-implied odds toward 25°C (44.5%) and 26°C (27%). Low precipitation risk and stable pressure support the upper end of the range, while any faster cooling or increased marine influence could cap readings near 24°C. Updated model runs and official Korea Meteorological Administration observations on October 4–5 will provide the final inputs for resolution.
