About this Market

Forecast models from sources including WeatherBug, WindBorne, and Meteum indicate a daily maximum of 27–29°C for Incheon on September 21 under clear to mostly sunny skies with light northerly winds and low humidity. This pattern reflects a stable high-pressure regime typical of early autumn in the region, producing moderate daytime heating without significant cloud cover or moisture to suppress temperatures. Historical September averages near 25–26°C provide context for the current outlook, while model consensus supports the market’s concentration on 27–28°C outcomes. Updated runs closer to the date could shift probabilities if steering patterns or insolation change.
