Traders see 25°C and 24°C as the most probable lows for Incheon on August 29 because official forecasts from the Korea Meteorological Administration and models like GFS show overnight minima near 24–25°C under mostly cloudy skies, high humidity near 85–90%, and light northwest winds that limit radiative cooling. Persistent moisture from the East Asian summer monsoon pattern reduces the temperature drop after daytime highs of 28–30°C, while scattered showers add further insulation. The tight 51.5–42.5% split reflects minor model differences in cloud timing and boundary-layer mixing, typical for late-August conditions where climatological lows average around 23°C. Updated evening observations and any clearing overnight could shift the final recorded minimum before resolution.
