Recent forecasts from the Korea Meteorological Administration and models like those referenced by AccuWeather show clearing skies after widespread rain and thunderstorms through August 17, setting up mostly sunny conditions on the 18th with daytime highs near 32–33°C. This transition reduces cloud cover and allows greater nocturnal radiative cooling, pushing overnight lows into the mid-20s Celsius range at Incheon. The near-even split between 24°C and 25°C market-implied odds reflects minor model divergences in wind patterns, humidity levels near 80%, and urban heat retention, all of which can shift the daily minimum by 1°C. Historical August averages for the region hover around 23–24°C lows, but the post-monsoon clearing favors slightly warmer readings absent stronger northerly flow. Updated short-range guidance expected within 24 hours will likely refine these probabilities.
