**Trader consensus has converged sharply on 19°C as the lowest temperature recorded in Seoul or Incheon on September 21, 2026, reflecting consistent official forecast guidance from multiple meteorological sources.** Clear to partly cloudy conditions under a stable high-pressure pattern have supported overnight radiative cooling, with model runs and station guidance converging on a minimum near 19°C (66°F) during the pre-dawn hours before daytime highs reach the upper 20s°C. This aligns with late-September climatology for the region, where typical overnight lows fall in the 17–20°C range absent strong frontal systems or cloud cover that would limit cooling. The market-implied odds above 98% indicate traders view deviations as low-probability given the narrow forecast spread and absence of disruptive weather. A realistic challenge would require either an unforecasted surge in wind or unexpected cloud cover reducing radiative losses, or a measurement revision at the primary station that shifts the observed minimum by 1–2°C. Updated observations from the Korea Meteorological Administration or Incheon International Airport would provide the decisive data for resolution.

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 21 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.**Trader consensus has converged sharply on 19°C as the lowest temperature recorded in Seoul or Incheon on September 21, 2026, reflecting consistent official forecast guidance from multiple meteorological sources.** Clear to partly cloudy conditions under a stable high-pressure pattern have supported overnight radiative cooling, with model runs and station guidance converging on a minimum near 19°C (66°F) during the pre-dawn hours before daytime highs reach the upper 20s°C.
