Ongoing heatwave conditions across South Korea, driven by a persistent high-pressure system, have pushed recent daily maxima in the Seoul-Incheon area to 34–39°C, with official KMA readings confirming elevated values earlier in the week. Forecasts for August 10 indicate moderation toward 32–34°C as increased cloud cover and possible shower activity reduce insolation, consistent with medium-range model consensus from KMA and international guidance. The close clustering of market-implied probabilities around these values reflects uncertainty in exact timing of any frontal passage or localized convection, which can shift peak readings by 1–2°C. Historical August climatology for Incheon shows typical highs near 30°C, underscoring how the current anomalous warmth supports the 33°C and 34°C outcomes as leading scenarios ahead of final observational data.
