Recent National Weather Service model consensus for Austin indicates a high near 98°F on September 21 under mostly sunny skies with light southeasterly flow and minimal precipitation risk, consistent with late-summer high-pressure patterns. This places the expected maximum well above the 1991–2020 average of 89.8°F but far below the all-time record of 102°F set in 2005, while heat indices may approach 105°F due to humidity. The near-even market-implied odds between sub-90°F and 108°F+ outcomes reflect genuine short-term forecast uncertainty, including potential steering pattern shifts or localized measurement variations at official stations, with updated NWS guidance and morning observations serving as the key resolution inputs in the next 48 hours.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Austin-Bergstrom International Airport Station in degrees Fahrenheit on 21 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=kaus
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
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 US Units w/ kts" button until the relevant table displays °F.
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 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 model consensus for Austin indicates a high near 98°F on September 21 under mostly sunny skies with light southeasterly flow and minimal precipitation risk, consistent with late-summer high-pressure patterns.
