Recent forecasts from the Korea Meteorological Administration and global models indicate a daytime high for Busan near 24–26°C on October 13, with scattered showers and thunderstorms expected through afternoon before clearing. Midday observations around 22–23°C, combined with southwesterly flow and high humidity, support a peak in the mid-20s rather than warmer or cooler extremes. Trader consensus around 25°C as the most likely outcome reflects model agreement on these conditions, while the spread to 24°C and 26°C captures remaining uncertainty in exact timing of peak heating and any localized variations before cooler northwest air arrives overnight.
