Recent forecasts from the Korea Meteorological Administration and international models indicate Seoul-Incheon overnight lows stabilizing near 27–28°C on August 7 amid an ongoing heatwave with daytime highs reaching 35–37°C. High humidity levels near 80% suppress radiative cooling under clear to partly cloudy skies, while weak synoptic forcing and light easterly winds limit advection of cooler air. This setup aligns with early-August climatology of 24–27°C minimums yet favors the upper end given persistent warm-air advection. Trader sentiment clusters tightly around 27–28°C because ensemble spreads show modest uncertainty in cloud cover and boundary-layer mixing that could shift the minimum by 1°C either way, with 29°C remaining viable if nocturnal temperatures hold higher than expected. Updated model runs and official briefings ahead of the date will likely refine these probabilities.
