Persistent heavy rain and extensive cloud cover over Seoul and Incheon on August 31 are suppressing nocturnal radiative cooling, keeping overnight lows tightly clustered near 22–24 °C. Official guidance from the Korea Meteorological Administration and numerical models show sustained easterly flow, high humidity above 90 %, and widespread precipitation that limits temperature drops after sunset, with hourly readings holding steady around 23–24 °C through the early morning. Minor differences among leading outcomes hinge on the precise timing and intensity of the heaviest rain bands and any brief wind shifts, which could allow slightly more or less cooling before sunrise. Updated model runs and the ongoing frontal system reinforce this narrow range, consistent with trader-implied probabilities that treat 22 °C, 23 °C, and 24 °C as nearly equiprobable.

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 31 Aug '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.
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 heavy rain and extensive cloud cover over Seoul and Incheon on August 31 are suppressing nocturnal radiative cooling, keeping overnight lows tightly clustered near 22–24 °C.
