This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Incheon Intl Airport Station in degrees Celsius on 1 Sep '26. The resolution source for this market will be information from NOAA, specifically the lowest 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 which 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 can not resolve until the first data point for the following date has been published on the resolution source. 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.
Persistent rain, cloud cover, and elevated dew points from ongoing thunderstorms have suppressed nocturnal radiative cooling across the Seoul-Incheon region on September 1, 2026, anchoring overnight lows near 21–23 °C according to official guidance and model consensus. High humidity near 90 % and light winds further limit the diurnal temperature range, consistent with early-September climatology modified by the active monsoon trough. Hourly observations through the night show temperatures stabilizing above 22 °C before any modest daytime recovery, supporting the dominant market-implied probability for a daily minimum of 21 °C while leaving only slim room for slightly cooler readings if clearing develops unexpectedly late.
