**Current forecasts for Busan on October 16 point to overnight lows near 14–15°C under a migratory high-pressure system, with mostly cloudy skies, light northeast winds, and minimal precipitation risk.** This setup produces typical autumn diurnal ranges of roughly 10°C between daytime highs near 24–26°C and cooler dawn readings, consistent with above-average conditions for mid-October. Model consensus across sources shows limited overnight cooling due to cloud cover and stable pressure around 1019–1025 hPa, reducing the chance of sharp drops below 10°C or spikes above 18°C. Trader balance between the 8°C-or-below and 18°C-or-higher bins reflects uncertainty in exact minimums from local topographic effects and minor forecast revisions before the 24-hour resolution window closes.
