Official Korea Meteorological Administration forecasts for August 17 project a maximum of 32°C under mostly cloudy skies with afternoon showers and 60% precipitation probability, moderating peak heating and aligning trader consensus around 28–30°C. Mid-August climatology for the Seoul-Incheon region centers on 29–31°C daily highs, but recent model runs incorporating increased moisture and reduced insolation from cloud cover and scattered convection favor outcomes slightly below the seasonal baseline. Afternoon thundershowers, common during the East Asian summer monsoon transition, limit surface warming by enhancing evaporative cooling and limiting direct solar radiation. No major shifts in steering patterns or upstream high-pressure systems have emerged in the latest 48-hour guidance to alter this range.
