This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Incheon Intl Airport Station in degrees Celsius on 9 Sep '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=rksi If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.**Trader sentiment for the highest temperature at Incheon International Airport on September 9, 2026, centers on 26°C as the consensus outcome.** Recent model runs and official Korea Meteorological Administration guidance show a cold, dry high-pressure system expanding from northern China, which has moderated temperatures after earlier September peaks near 30–31°C. This setup favors a daytime maximum of 24–26°C under mostly clear to partly cloudy skies, with light easterly winds and minimal cloud cover limiting further warming. Current observations near midday hover around 23°C, aligning with the forecast trajectory toward a peak near 26°C. Historical September baselines for Incheon typically range 24–27°C, providing context for why probabilities cluster tightly around these values rather than extremes. Updated forecasts and any late-day observations will refine resolution near the close of the 24-hour period.
