Ongoing heatwave conditions driven by a strong North Pacific High and heat-dome pattern are sustaining above-average maximum temperatures across the Seoul-Incheon region, with Korea Meteorological Administration guidance indicating daytime peaks near 33–34°C for August 3. Ensemble forecast models show close agreement on this range amid typical summer humidity and limited initial precipitation, though minor variations in cloud cover, wind patterns, or timing of any frontal influences could shift the daily high by 1°C. Historical August climatology places average highs around 31°C, making the current setup notably warmer, while uncertainty in short-range model runs explains the tight market-implied odds between 33°C and 34°C outcomes.
