Recent KMA forecasts indicate showers and thunderstorms likely over Busan on August 17, with 60% precipitation probability in the afternoon and maximum temperatures projected near 31–32°C under partly cloudy conditions. This coastal setting, influenced by southerly flows along the North Pacific High, produces typical August highs of 29–31°C, but variable cloud cover and evaporative cooling from rain differentiate outcomes around 27–29°C. Ensemble models show modest disagreement on shower timing and intensity, with earlier or heavier precipitation favoring the 27°C or 28°C bins while delayed clearing supports 29°C. Traders weigh these short-term dynamics against climatological baselines, as official KMA station data will resolve the market.
