Ongoing heatwave conditions driven by a strong high-pressure ridge over the Korean peninsula are sustaining elevated temperatures, with the Korea Meteorological Administration forecasting a 34°C daytime maximum for Incheon on August 11 under clear skies and negligible precipitation. Ensemble model runs indicate limited variability from solar insolation and minimal overnight cooling due to high humidity, keeping outcomes clustered around 32–34°C. Recent national records exceeding 42°C earlier in the month highlight how persistent anticyclonic patterns can push readings 2–4°C above climatological August averages of 29–31°C. Traders are closely monitoring the next KMA update and any shifts in steering flow that could introduce marine influence from the Yellow Sea or brief cloud cover, differentiating the tightly matched leading probabilities.
