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 9 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 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 forecast model runs from sources including the Korea Meteorological Administration and international ensembles indicate overnight lows in Incheon on September 9 clustering between 17–20°C under persistent high pressure, clear skies, and northeasterly winds of 7–10 m/s that limit boundary-layer mixing. This setup favors radiative cooling after daytime highs near 26°C, though small differences in cloud cover, wind strength, or dew-point advection can shift the minimum by 1–2°C. Market-implied odds near 19–20°C capture the narrow spread between guidance showing stronger cooling versus slightly warmer advection, with historical early-September Incheon minima averaging around 17–18°C providing context for the tight distribution. Updated KMA and ensemble outputs expected overnight will likely refine the final range.
