Traders assign the highest implied probabilities to overnight lows of 25–26°C for Seoul on July 30, reflecting near-term forecast consensus from models such as those issued by the Korea Meteorological Administration. Typical late-July climatology features humid subtropical conditions with minimum temperatures averaging 24–26°C, modulated by cloud cover, wind speed, and boundary-layer moisture that limit nocturnal radiative cooling. Scattered showers and variable high humidity in recent days have kept surface temperatures elevated, narrowing the range between 24°C and 27°C outcomes while reducing the likelihood of extremes below 23°C or above 28°C. Updated short-range guidance over the next 48 hours will refine these probabilities as forecasters incorporate the latest ensemble runs and local observations.
