Trader consensus on a 19°C low for Seoul/Incheon on September 20, 2026, reflects official and model-aligned observations showing overnight minima stabilizing near that threshold under clear, calm conditions with northerly flow. Regional forecasts from agencies and airport stations consistently placed the daily minimum between 18–20°C, with hourly readings bottoming around 18–19°C in the pre-dawn hours before rapid daytime warming to 28–29°C. This outcome aligns with typical early-autumn climatology for the region, where radiative cooling under dry, high-pressure influence produces such readings. Only an unexpected late-night surge in cloud cover, wind shift, or measurement discrepancy between Seoul and Incheon stations could realistically alter the recorded low.

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.
