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 4 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.
Recent official forecasts from the Korea Meteorological Administration and international models (Met Office, AccuWeather, Yr) converge on a daytime high of 29–30 °C in Seoul/Incheon for September 4 under clear skies and light northeasterly flow. A surge of cooler, drier air from the north has suppressed overnight lows while allowing strong daytime solar heating, with dew points near 18–20 °C supporting efficient warming to peak levels around 15:00 local time. These conditions align with the market’s heaviest weighting on 29–30 °C outcomes, as traders incorporate the latest model runs showing limited upside beyond 31 °C and negligible risk of sub-28 °C readings. Updated guidance through the evening of September 3 will be the next key input before resolution.
