Recent forecasts from the Korea Meteorological Administration and ensemble models indicate clearing skies over the Seoul-Incheon region on August 23 after widespread rain and cloud cover through August 22, allowing maximum temperatures to recover toward 30–34 °C amid residual high humidity and the influence of the North Pacific high. Official guidance places Incheon highs near 29–31 °C with localized peaks to 33 °C possible under stronger insolation, consistent with climatological norms for late August near the Cheoseo seasonal transition. Model spread and steering flow uncertainty keep the distribution centered on 30–32 °C, explaining the market’s emphasis on those three outcomes while limiting odds of extremes above 34 °C. Updated KMA guidance and morning model runs on August 22–23 remain the key near-term catalysts.
