Recent Korea Meteorological Administration forecasts indicate a maximum of 31°C for Incheon on August 22 amid persistent cloud cover, light easterly winds, and a 60% chance of rain, which limits daytime heating by reducing solar insolation and enhancing evaporative cooling. Trader consensus clusters around 28–30°C because model ensembles show sensitivity to the precise timing and intensity of showers, with even modest increases in cloud thickness or earlier precipitation potentially capping the peak 1–2°C lower while clearer intervals could push it toward 31°C. This aligns with typical late-August climatology of 29–30°C highs under similar synoptic patterns, where humidity near 75% further modulates realized temperatures through latent heat effects. Updated model runs and hourly observations over the next 48 hours will likely refine the distribution.
