**Trader sentiment clusters tightly around 34–36°C for Busan’s July 26 maximum because short-range ensemble forecasts from the Korea Meteorological Administration and global models show a narrow spread centered near 31–35°C, with modest upside risk if daytime heating strengthens under partly cloudy skies.** Coastal sea breezes and high humidity typical of Busan’s summer regime often cap afternoon peaks, while scattered showers or thicker cloud cover can suppress readings by 1–3°C. Recent seasonal outlooks for above-average July temperatures across southern Korea provide slight upward pressure, yet the two-day lead time leaves room for last-minute shifts in the steering flow or convective development that could easily move the outcome between the three leading bins.
