Official National Weather Service observations recorded a maximum of 88°F at Denver on August 18, locking in the market's 100% consensus on the 88-89°F bin. This outcome aligned with NWS and ensemble model guidance showing modest warming above the 87°F seasonal normal under mostly sunny skies, light southeast flow, and moderate dew points that limited mixing and supported incremental afternoon heat buildup. Historical August climatology and recent model runs had narrowed expectations to the upper 80s–low 90s range, with the precise measurement reflecting typical late-summer boundary-layer conditions without significant convective cooling. Only major forecast busts or station data revisions could have altered resolution.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Buckley Space Force Base Station in degrees Fahrenheit on 18 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Buckley Space Force Base Station, available here: https://www.wunderground.com/history/daily/us/co/aurora/KBKF.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
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.
