Recent forecasts from multiple models indicate a high near 24–26°C in Incheon on September 25, driven by increasing cloud cover, southeasterly flow, and a 50–80% chance of afternoon showers that limit afternoon heating. These conditions follow several days of clearer, warmer weather near 28–29°C, with the expected moisture influx and reduced insolation creating the tight clustering of market-implied odds around the middle outcomes. Historical late-September averages near 23–25°C provide baseline context, while minor model differences in timing of precipitation and wind shifts account for the spread across 23–27°C. Updated runs from the Korea Meteorological Administration and global ensembles over the next 48 hours will likely narrow the range before 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.
