**Strong model consensus from official forecasts positions the overnight minimum at Incheon International Airport near 20°C, driving the 99.4% market-implied probability.** Clear skies and light northeasterly winds have supported steady radiative cooling through the evening, aligning with seasonal early-September norms where typical lows range 18–21°C. Multiple sources, including WeatherBug, Met Office, and Yr.no guidance, converge on a minimum of 19–20°C (67–68°F) with minimal precipitation risk or temperature deviation expected before midnight. This skin-in-the-game trader consensus reflects high confidence in the aggregated forecast ensemble. Realistic challenges include minor observational differences between Seoul city stations and Incheon, late-evening cloud increases, or localized wind shifts that could nudge the recorded low by 1°C, though current conditions make such shifts improbable. Official Korean Meteorological Administration daily summary will resolve the market.

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.
