Recent forecasts for Busan point to a highest temperature near 31–34°C on August 22, with scattered thunderstorms and overcast skies from the lingering influence of the North Pacific High and possible frontal activity expected to moderate peak heating. Official Korea Meteorological Administration guidance and ensemble models show modest day-to-day variability driven by cloud cover, humidity levels above 70 percent, and coastal sea breezes that can shave 1–2°C off inland maxima. The market’s broad distribution across 32–34°C reflects uncertainty in exact storm timing and intensity, consistent with typical late-August variability where historical averages sit near 30–31°C but recent early-month heatwave conditions have kept trader sentiment slightly elevated. Updated short-range model runs over the next 48 hours will likely tighten the range.
