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 3 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 from the Korea Meteorological Administration (KMA) and global ensembles currently indicate an afternoon maximum of 29–31 °C at Incheon International Airport on September 3, 2026, under partly cloudy to clear skies with light northerly winds. This consensus drives the market’s heavy weighting toward 30 °C (50 %) and 31 °C (23.5 %), followed by 29 °C (19.5 %). High pressure and subsidence are expected to suppress cloud cover and precipitation after earlier showers, allowing strong daytime heating while moderate humidity and a light northeasterly breeze limit extreme warming. Official short-range guidance lists a maximum near 29 °C, with some ensemble members reaching 30–31 °C depending on boundary-layer mixing and insolation. Historical early-September climatology for the station centers around 27–28 °C, so the current setup represents slightly above-average warmth but remains well within normal variability. The next model updates from KMA and global centers will refine the precise peak, particularly if wind speeds or cloud timing shift.
