**Recent forecasts from the Korea Meteorological Administration and international models indicate a minimum temperature for Busan on August 28, 2026, most likely in the 23–26 °C range, driven by widespread cloud cover and intermittent rain associated with a lingering frontal system.** High humidity (often above 80–85 %) and reduced radiative cooling under overcast skies are limiting overnight temperature drops, while daytime maxima are expected to reach only 29–31 °C. This produces a relatively narrow diurnal range compared with typical late-August conditions. Model consensus shows light-to-moderate precipitation continuing into the evening of the 28th, which further stabilizes nighttime temperatures near 25–26 °C in many runs, though slight variations in rain timing or wind direction can shift the exact minimum by 1–2 °C. Trader-implied odds clustered tightly around 24–26 °C (each near 44–45 %) reflect this genuine forecast uncertainty rather than a single dominant outcome, consistent with the wisdom-of-crowds assessment of short-range model spread and the resolution criteria tied to official station observations.
