Recent forecasts from multiple models indicate Busan will experience widespread cloud cover and thunderstorms on August 28, driven by enhanced moisture transport and a passing frontal system that reduces solar insolation and limits daytime heating. Official guidance points to a maximum temperature near 27–28°C, consistent with climatological norms for late August but tempered by high humidity and precipitation probabilities exceeding 80%. Trader consensus around 50% odds for each threshold reflects model spread in exact timing and intensity of rain, which can alter peak readings by 1–2°C through evaporative cooling or brief clear spells. Updated runs from agencies like the Korea Meteorological Administration will refine these variables ahead of market resolution.
