Forecasts from the Korea Meteorological Administration indicate a daytime maximum near 33°C for Incheon on August 13 under initially clear then increasingly cloudy skies, following a multi-week heatwave that produced peaks above 37°C earlier in the month. Trader consensus clustering between 31–32°C reflects model spreads on peak timing, modest afternoon cloud cover reducing insolation, and local sea-breeze moderation typical for the coastal station. Low precipitation probability and light winds limit cooling, yet ensemble guidance shows slight downward revisions from earlier outlooks. Resolution hinges on the official Incheon station reading, with new hourly observations and updated KMA guidance expected to narrow remaining uncertainty before sunset.
