Recent Korea Meteorological Administration and ensemble model guidance indicate persistent high-pressure ridging over the Korean Peninsula, sustaining elevated temperatures into August 8 amid an active heatwave. This setup favors daytime maxima near 34–36 °C at the Incheon station, with subtle differences among leading outcomes driven by forecast uncertainty in boundary-layer moisture, the timing and strength of any sea-breeze circulation from the Yellow Sea, and the potential for limited afternoon cloud cover or weak convection that could cap peak readings. Historical early-August climatology shows typical highs around 31 °C, so current anomalies reflect stronger-than-normal subsidence and urban heat retention, though small shifts in steering flow or moisture advection could easily move the outcome between the closely matched 34 °C, 35 °C, and 36 °C bands.
