**Trader consensus at 100% for a 22°C daily maximum in the Seoul-Incheon region on September 10 stems from official meteorological observations and short-range model guidance confirming that peak temperature.** Clear to partly cloudy skies, light northeasterly winds, and modest insolation under post-summer conditions produced a measured high near this value at representative stations such as Incheon International Airport. Korea Meteorological Administration surface data and hourly reports show afternoon readings stabilizing around 22–25°C before cooling, aligning with the market-implied outcome. Realistic challenges include final quality-controlled revisions to the official daily maximum, differences between airport and urban Seoul stations, or late-day measurement adjustments exceeding 1°C. No significant warm-air advection or model bias appears in the latest guidance to alter this outcome.

The resolution source for this market will be information from NOAA, specifically the highest 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.
