Recent forecasts from agencies including the Korea Meteorological Administration and global models show a cooling trend into August 30, with Incheon highs most likely in the 26–28°C range amid increasing cloud cover, light rain, and northerly flow moderating daytime heating. High humidity and scattered showers from lingering monsoon influences limit surface warming despite peak solar angles, while wind patterns and overnight lows near 23°C further constrain the daily maximum. Trader sentiment clusters tightly around these outcomes because ensemble guidance shows modest spread, with 27°C slightly favored due to recent model runs aligning on partial clearing. Historical late-August baselines near 29°C highlight how the current moisture surge has shifted probabilities lower, though any delay in precipitation could push readings toward 29°C.
