Current forecast models from agencies including the Korea Meteorological Administration highlight a potential influx of cooler northerly air and clear overnight conditions on September 8, supporting radiative cooling that could push Incheon’s low into the mid-teens Celsius. This aligns with the market’s leading 43% implied probability on 15°C or below, exceeding the typical early-September climatological range of 17–19°C. Recent model runs show modest spread around wind direction and cloud cover, which traders weigh against historical September minima near 15–16°C during transitional periods. Updated ECMWF and GFS outputs expected within the next 24–48 hours will likely refine the overnight minimum before resolution.

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.
