Recent forecasts from multiple models converge on a maximum temperature of 24–26°C for Incheon on September 15 under clear to mostly sunny conditions with light northwest winds and negligible precipitation risk. This consensus underpins the market’s heavy weighting toward 25°C as the leading outcome, followed by 26°C and 24°C. Seasonal climatology supports these values, as mid-September daily highs in the Seoul metropolitan area typically range from 24–27°C before cooler autumn air masses arrive. Model agreement on stable high pressure and modest daytime heating leaves little room for significant upside or downside surprises, though minor revisions in the final forecast runs could still shift probabilities among the three central outcomes.

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.
