Recent KMA forecasts for August 16 indicate mostly cloudy conditions with a 20% chance of precipitation and a projected daytime maximum near 33°C for the Seoul-Incheon area, though ensemble spread and coastal marine influence introduce notable uncertainty in peak values. Persistent humidity and weak steering flow limit daytime heating compared with the early-August heatwave, while variable cloud cover and any scattered showers could suppress temperatures by 2–4°C relative to clearer scenarios. Historical August maxima average 30–31°C, providing climatological context for the tight clustering of market-implied probabilities around 28–30°C. Updated model runs and official KMA briefings in the next 48 hours will refine the most likely range before resolution.
