**Current forecasts from multiple meteorological sources converge on a daytime maximum of 23–24°C for Busan on October 6, driven by clear skies under a northwest flow of drier continental air.** This setup favors modest daytime heating from solar insolation while limiting moisture and cloud cover that could enhance warming or suppress it through reflection. Northwest winds advect cooler air from higher latitudes, capping the peak near the seasonal average of roughly 23°C, with low humidity (around 30–50%) and negligible precipitation risk reinforcing stable conditions. Recent model runs show little deviation, supporting the market’s heavy weighting toward 24°C (51.5%) and 23°C (30.5%), while the slim odds on 25°C reflect only minor upside potential if winds weaken or insolation exceeds expectations. With resolution hours away, updated observational data from the Korea Meteorological Administration will be the final arbiter.
