Recent forecasts from multiple models indicate a high near 22–24°C for Busan on October 2 under predominantly sunny skies and light northwest to easterly winds, close to the early-October climatological average of about 22°C. The near-even split between 24°C and 25°C reflects minor differences in expected peak solar heating, boundary-layer mixing, and local sea-breeze effects that can add or subtract 1–2°C at the observation site. With negligible rain chances and stable high pressure, temperature variance hinges on the precise timing of maximum insolation and any late adjustments in model guidance. Updated runs from agencies such as the Korea Meteorological Administration will likely resolve the narrow gap before resolution.
