Forecasts from the National Weather Service and other meteorological sources indicate Austin overnight lows on August 21 will settle in the upper 70s, with morning readings near 78°F under mostly clear skies and light southerly winds. Persistent high pressure and elevated dew points from the ongoing heat wave have limited radiational cooling, keeping minimum temperatures well above seasonal averages around 75°F. Traders have clustered probability on the 76–79°F bins, reflecting model consensus for minimal overnight drop despite daytime highs exceeding 100°F. Subtle variations in wind patterns or cloud cover could nudge readings a degree or two, but current conditions point to a narrow range near the upper end of typical August nights.

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 Austin-Bergstrom International Airport 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 Austin-Bergstrom International Airport Station, available here: https://www.wunderground.com/history/daily/us/tx/austin/KAUS.
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.
