Latest Korea Meteorological Administration forecasts project a daytime maximum of 33°C in Busan on August 19 under mostly cloudy skies with limited precipitation, aligning with ensemble model consensus from regional guidance. This outlook stems from persistent late-summer subtropical high pressure, warm sea-surface temperatures in the Korea Strait moderating extreme heat while sustaining high humidity, and typical August climatology where Busan averages near 29–30°C. Traders have concentrated implied probabilities on 31–33°C ranges because short-range numerical weather prediction runs show low variability in steering patterns and minimal cold-air advection over the next 48 hours. Updated model runs and official briefings through August 18 will provide the next key data points for refining these market-implied odds.
