Official forecasts from the Korea Meteorological Administration project a 24°C minimum temperature for Seoul and Incheon on August 18, 2026, under mostly clear to partly cloudy skies with light winds and minimal precipitation risk. This aligns with typical mid-August climatology, where overnight lows commonly stabilize near 24°C amid high humidity and daytime highs around 33°C. The near-certain market-implied odds reflect strong model consensus and the absence of disruptive atmospheric features such as cold fronts or enhanced cloud cover that could produce further cooling. Resolution depends on verified morning lows recorded between 3–9 a.m. local time at official stations; only a substantial, unforecasted temperature drop below 24°C would alter the outcome.
