Recent forecasts from the Korea Meteorological Administration and global models indicate a high-pressure system dominating the region, with clear skies and northwesterly flow expected to limit daytime warming on October 2. This setup aligns with early-autumn climatology, where Seoul and Incheon typically see highs of 20–22°C amid cooling after summer. Current model consensus supports afternoon peaks near 21°C, with 22°C plausible if insolation maximizes before winds strengthen; lower outcomes remain unlikely absent unexpected cloud cover or frontal activity. Traders appear to weigh these stable conditions heavily, with implied probabilities reflecting tight clustering around the historical baseline and minimal forecast spread. Updated model runs and official briefings tomorrow morning represent the next key data points.
