Recent National Weather Service and model consensus forecasts position the highest temperature in Chicago on August 25 around 78–81°F, with mostly sunny skies, light southerly winds, and minimal cloud cover limiting afternoon heating. This aligns with current atmospheric conditions featuring a northwest flow and no significant warm advection or high-pressure ridge strengthening. Historical climatology shows an 81.7°F average high for the date, but recent cooler upstream air masses have kept forecasts several degrees below normal. Traders appear to weigh the tight clustering of official guidance and ensemble outputs, which show low probability of exceeding 83°F or falling below 78°F absent unexpected model shifts before resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 25 Aug '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=kord
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). 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 National Weather Service and model consensus forecasts position the highest temperature in Chicago on August 25 around 78–81°F, with mostly sunny skies, light southerly winds, and minimal cloud cover limiting afternoon heating.
