**Forecast models from multiple sources, including the Korean Meteorological Administration and international providers like the Met Office and PredictWind, indicate a daytime high of 27–28°C for Incheon/Seoul on September 18, 2026, under partly cloudy skies with easterly winds of 5–9 m/s and minimal precipitation risk.** This positioning stems from a stable high-pressure regime typical of mid-September transition season, following seasonal cooling from summer peaks and without incoming fronts or tropical systems. Recent observations show highs near 27–28°C on the 16th–17th, with diurnal ranges of 10–12°C and dew points supporting moderate humidity around 50–65% during peak heating hours. Model consensus clusters tightly around these values, with minor spread allowing limited upside to 29°C if afternoon insolation strengthens or slight warm advection occurs, while downside to 27°C or below remains possible if cloud cover increases. The market-implied odds (28°C leading at 53%) reflect this narrow uncertainty band, consistent with high-confidence short-range numerical weather prediction for the region. Updated model runs or official KMA briefings on the 18th morning will provide the final resolution inputs.

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.
