Latest ensemble forecasts from global and regional models indicate overnight lows of 21–23°C for Incheon on September 3 under building high pressure, clear to partly cloudy skies, and moderate northeasterly flow that limits mixing while permitting radiational cooling after a warm, humid daytime. Primary uncertainties differentiating the tightly clustered 21–23°C outcomes include small variations in boundary-layer humidity, wind speeds near 5–8 km/h, and residual moisture from recent showers that can alter surface energy balance and dew-point depression. These factors create modest spread across model runs, which traders aggregate into current market-implied odds favoring 22°C.

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.
