Recent forecasts from official sources including the Korea Meteorological Administration and international models indicate a high of 25–27°C for Incheon on September 9, with peak readings most likely near 26°C during afternoon hours under partly cloudy skies and northeast winds of 7–10 m/s. This consensus, driven by high-pressure dominance and cooler maritime air advection following warmer conditions on September 8, underpins the market-implied probabilities favoring 26°C at 49%. Model runs show limited spread due to stable steering patterns and minimal convective activity, though minor variations in cloud cover or wind timing could shift the daily maximum by 1°C. Historical September averages near 24–25°C provide context for the slightly elevated but not extreme outlook.

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 9 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.Recent forecasts from official sources including the Korea Meteorological Administration and international models indicate a high of 25–27°C for Incheon on September 9, with peak readings most likely near 26°C during afternoon hours under partly cloudy skies and northeast winds of 7–10 m/s.
