Recent forecasts from the Korea Meteorological Administration and international models indicate a likely overnight low of 24–25°C for Incheon on August 22, with trader consensus tightly clustered around these values amid lingering summer humidity and variable cloud cover. Persistent easterly flow and elevated dew points near 24°C are limiting radiational cooling, while scattered showers through Friday could further moderate temperature drops depending on timing and intensity. Historical climatology places the typical August 22 minimum near 23°C, but current model spreads reflect uncertainty in cloud persistence versus partial clearing that would allow slightly greater cooling toward 23°C or hold readings near 25°C. Updated KMA guidance and next model cycles will likely refine the range before resolution.
