Recent forecasts from the Korea Meteorological Administration and international models indicate a high near 23–25°C for Incheon under mostly clear to partly cloudy skies, light northeast winds, and stable high pressure. These conditions favor modest afternoon warming without significant cloud suppression or advection of cooler air. Trader consensus clusters on 23°C and 24°C because small differences in peak timing, exact insolation under variable cloud cover, and minor discrepancies between Seoul urban and Incheon coastal stations can shift the recorded maximum by 1°C. Historical September averages near 25°C provide context, yet current model runs and early-day observations support the tight 37.5–36.5% split on the two leading outcomes. Updated hourly readings and any late-day model revisions remain key resolution inputs.

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.
