Recent forecasts from the Korea Meteorological Administration indicate mostly cloudy skies and a 30% chance of precipitation over the Seoul-Incheon area on August 15, supporting a daily maximum near 30–32 °C amid lingering subtropical moisture and weak steering winds typical of mid-August climatology. Trader consensus clustering around 29 °C and 30 °C reflects uncertainty in how much daytime cloud cover and any scattered showers will suppress peak readings at the coastal Incheon station, which often runs 1–2 °C cooler than inland Seoul due to marine influence. Recent model runs show limited diurnal heating under high humidity, keeping probabilities balanced between these bins while downweighting 31 °C or higher outcomes. Updated short-range guidance expected later today will clarify whether any clearing trend emerges to push temperatures toward the upper end of the range.
