Current forecasts from multiple models indicate a minimum temperature near 24–25°C for Busan on September 3, with partly cloudy skies, scattered showers, and northeast winds of 8–15 mph moderating overnight cooling. Trader sentiment remains closely split because ensemble guidance shows notable spread in radiative cooling under variable cloud cover and humidity, with some runs supporting minima near or above 27°C while others allow brief dips toward 21–22°C. This uncertainty stems from the timing of any rain bands and the strength of onshore flow, typical for early September when sea surface temperatures remain elevated. Fresh model updates and observational data from the Korea Meteorological Administration over the next 48 hours will likely narrow the range ahead of market resolution.
