Forecast models from agencies including the Korea Meteorological Administration indicate a weather system bringing clouds and showers to the Seoul-Incheon region on August 29, which limits daytime heating and caps maximum temperatures. Official outlooks project highs of 27–29 °C, consistent with late-August climatology where average daily maxima near 30 °C decline amid increased precipitation. Thunderstorm activity and associated cloud cover reduce solar insolation, while steering patterns and humidity levels further moderate peaks. Trader consensus reflected in the closely matched probabilities for 28–30 °C captures residual uncertainty in exact model runs and timing of any clearing, with new guidance from regional forecasts likely to refine the range before resolution.
