**Forecast models and observational data from sources including the Global Forecast System (GFS) and regional analyses indicate a maximum temperature of 25°C at Incheon on September 11, 2026, under mostly cloudy to overcast skies with light northwest winds and minimal precipitation risk.** Afternoon readings have hovered near or slightly below this level, consistent with seasonal September norms for the region and the absence of strong warm advection or clear-sky heating. Market-implied odds near 99% for 25°C reflect trader confidence in this consensus, as multiple independent runs converge on the same threshold. A realistic shift could occur only if post-3 PM observations at the official station register 26°C due to brief clearing or measurement variability, though current conditions and model agreement make this improbable before resolution.

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 11 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.**Forecast models and observational data from sources including the Global Forecast System (GFS) and regional analyses indicate a maximum temperature of 25°C at Incheon on September 11, 2026, under mostly cloudy to overcast skies with light northwest winds and minimal precipitation risk.** Afternoon readings have hovered near or slightly below this level, consistent with seasonal September norms for the region and the absence of strong warm advection or clear-sky heating.
