Recent forecasts from the National Weather Service and AccuWeather project overnight lows near 63°F for Denver on August 21, 2026, aligning with late-summer norms of 57–58°F at Denver International Airport while reflecting elevated readings from recent warm minima. Clear skies and light winds promote radiational cooling at the mile-high elevation, yet scattered thunderstorms and residual moisture from upstream patterns may limit how far temperatures drop. Trader consensus clusters on 64–69°F ranges because model guidance shows modest variability in cloud timing and boundary-layer mixing, with official minimums measured via standardized ASOS instrumentation. Historical analogs indicate August 21 lows typically range 45–72°F, underscoring the narrow window for resolution as the calendar day concludes.

This market will resolve based on the lowest 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 lowest temperature recorded at the Buckley Space Force Base Station in degrees Fahrenheit on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
