**Persistent late-summer heat and high humidity across southern South Korea, combined with a stationary front delivering showers and thunderstorms, are positioning 31–33 °C as the leading outcomes for Busan’s August 29 daily maximum.** Official forecasts from the Busan Meteorological Office and regional models show daytime highs of 30–32 °C on Saturday amid partly cloudy skies, southwesterly flow, and dew points near 27–28 °C that limit nocturnal cooling and support elevated afternoon readings on the Celsius scale. Recent heat advisories and tropical-night conditions have kept perceived temperatures around 33 °C, while scattered rainfall has not produced the stronger cooling often seen with organized systems. Trader consensus reflected in the 44.5 % implied probability for 32 °C aligns with this pattern of modest day-to-day variability typical for coastal Busan in late August, with new model runs and local observations expected to refine the exact peak before resolution.
