Forecast models, including GFS data, indicate a daytime high near 26°C in Incheon on September 14 under partly cloudy to overcast skies with northwest winds of 10–15 km/h and negligible precipitation risk. Current conditions on September 13 show overnight lows in the upper teens Celsius transitioning to afternoon peaks in the mid-20s, consistent with seasonal norms for mid-September and lacking strong synoptic drivers for significant deviation. Trader positioning favoring 26°C over nearby outcomes reflects this model consensus, tempered by typical forecast uncertainty ranges of 1–2°C from variables like cloud cover or wind shifts. Final Incheon station observations will determine resolution.

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.
