Current forecast models from sources including NOAA-aligned and regional analyses indicate Busan will see a high near 23–24°C on October 4 under mostly overcast to partly cloudy skies, northeasterly winds of 6–10 mph, and low precipitation chances. This places the daily maximum close to seasonal norms for early October in the region. Trader consensus favoring 25–26°C (combined ~81% implied probability) over the lower-probability 24°C outcome reflects model spread in afternoon warming potential, subtle variations in cloud timing, and the narrow margin between observed peaks and resolution thresholds. Short-range uncertainty in boundary-layer mixing and sea-surface influences keeps probabilities closely matched between the top two outcomes. Updated model runs and observational data ahead of peak heating will likely refine these odds.
