**Clear, stable high-pressure conditions under northeasterly flow are positioning 27°C as the most probable high temperature for Seoul/Incheon on September 20.** Official guidance from the Korea Meteorological Administration and multiple global models consistently forecast a sunny day with light winds and minimal cloud cover, yielding daytime maxima near 27–28°C (80–82°F) after overnight lows around 18–19°C. This aligns with the current market-implied odds, where 27°C leads at 43.5% followed by 26°C at 32.5%, reflecting trader consensus on limited diurnal warming potential amid seasonal cooling trends. Recent observations show similar highs of 28–29°C on September 18 under partly cloudy skies, with no incoming fronts or moisture expected to alter the pattern before the market resolves. Updated model runs and KMA briefings in the next 24–48 hours will provide the final confirmation ahead of the daily maximum measurement.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Incheon Intl Airport Station in degrees Celsius on 20 Sep '26.
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.**Clear, stable high-pressure conditions under northeasterly flow are positioning 27°C as the most probable high temperature for Seoul/Incheon on September 20.** Official guidance from the Korea Meteorological Administration and multiple global models consistently forecast a sunny day with light winds and minimal cloud cover, yielding daytime maxima near 27–28°C (80–82°F) after overnight lows around 18–19°C.
