Recent forecasts from the Korea Meteorological Administration and international models indicate persistent warm, humid conditions over Seoul and Incheon through late August, with overnight radiative cooling limited by high humidity, cloud cover, and light winds. This setup supports minimum temperatures clustering around 25–26°C for August 26, aligning with the market’s leading implied probabilities. Historical August lows average near 22–24°C, but the current late-summer pattern—marked by daytime highs near 32°C and minimal frontal activity—has kept recent observed minima elevated at 24–25°C. Overcast skies expected on the 26th further reduce the chance of sharper nocturnal drops, while any model consensus on steering patterns or precipitation timing has not yet signaled a shift toward cooler air. Updated short-range guidance and official observations in the next 48 hours will refine these thresholds ahead of market resolution.
