Recent forecasts for Incheon indicate a highest temperature near 28–30 °C on August 28, driven by persistent cloud cover, scattered showers, and light easterly flow that limit daytime heating. These conditions introduce uncertainty between the 27 °C and 30 °C bins because even modest increases in insolation or reduced rainfall could push maxima higher, while heavier convective activity would enhance evaporative cooling and keep readings lower. Late-August climatology shows a gradual seasonal decline from peak summer warmth, and model consensus remains sensitive to small shifts in steering patterns or moisture advection ahead of the next update from the Korea Meteorological Administration.
