**Forecast models from sources including the Korea Meteorological Administration and global ensembles indicate a high of 27–28°C for Seoul/Incheon on September 18 under partly cloudy skies with easterly flow and minimal precipitation risk.** This consensus, supported by recent observations of stable high pressure and temperatures reaching 26–28°C on prior days, positions 28°C as the market favorite at 53% implied probability, followed by 29°C (24.5%) and 27°C (21%). Typical mid-September climatology in the region features daytime maxima near 26–28°C with low variability absent strong synoptic changes. Light winds and moderate humidity are expected to limit further warming or cooling, keeping the distribution tightly clustered. Updated model runs or surface observations on the morning of the 18th represent the key near-term variables that could shift final readings within this narrow range.

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.
