Recent Korea Meteorological Administration forecasts and ensemble model runs indicate moderating heatwave conditions over Seoul-Incheon by August 10, with daytime maxima most likely reaching 33–34°C under partly cloudy skies and light winds. This follows peak readings near 39°C earlier in the week, driven by a weakening high-pressure ridge and increasing moisture that could limit further warming. Traders assign the highest implied probability to 33°C because subtle differences in cloud timing, humidity, and boundary-layer mixing across updated runs favor that threshold over 34°C or cooler outcomes near 32°C. Official Incheon station measurements will resolve the market based on the single highest hourly or daily peak.
