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 Austin-Bergstrom International Airport Station in degrees Fahrenheit on 17 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 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.

Official forecasts from the National Weather Service and model consensus currently point to a daily maximum near 102°F in Austin on August 17 under a strong upper-level ridge that promotes subsidence, clear skies, and efficient daytime heating during the climatological peak of summer heat. This setup aligns with the first half of August, when average highs reach 99°F and multi-day stretches above 100°F are common. Recent model runs show minimal spread, supporting the market's leading 102-103°F outcome at 49.5% implied probability, followed by 100-101°F at 27.5%. Any late adjustments to the ridge position or unexpected moisture could shift the peak within the 100-105°F range before resolution.
