Ongoing extreme heat across South Korea, driven by a dominant North Pacific High, keeps trader focus on whether Seoul/Incheon reaches the mid-30s Celsius on August 9. Korea Meteorological Administration data show the region under heatwave conditions with daytime maxima influenced by subsidence, low-level moisture, and variable cloud cover that can suppress peaks by 1–3 °C. Recent model runs indicate a narrow window around 33–35 °C at the Incheon station, with slight spreads arising from steering flow uncertainties and potential localized showers. Historical August baselines near 31 °C underscore how the current synoptic pattern elevates odds for the leading 33–34 °C outcomes while leaving room for upward or downward revisions as new KMA guidance arrives.
