Current short-range forecasts from global models and regional analyses indicate overnight lows in Busan on October 9 will likely reach 15–17°C under clear to partly cloudy skies, light northeasterly winds, and stable high pressure. These conditions favor radiative cooling after daytime highs near 24°C, aligning with early-October climatology where minimums average 16–18°C. Trader consensus reflected in the 49% implied probability for 20°C or higher versus elevated odds near 14–17°C captures model spread and potential for slight revisions in the final runs ahead of resolution. No major synoptic shifts are expected to alter the mild pattern significantly before the date.
