Official NWS Houston forecasts for August 22 indicate a high near 100°F under persistent upper-level high pressure promoting clear skies, light southwest winds, and strong solar heating, with dew points in the low 70s supporting elevated heat indices above 108. Recent model runs show minor spread between 99–102°F depending on the timing and coverage of any isolated afternoon convection, explaining the tight market clustering around 98–101°F. Historical August baselines near 95°F and ongoing heat-advisory conditions reinforce trader focus on whether subtle steering changes or boundary-layer mixing push the peak slightly above or below 100°F before 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 William P. Hobby Airport Station in degrees Fahrenheit on 22 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 William P. Hobby Airport Station, available here: https://www.wunderground.com/history/daily/us/tx/houston/KHOU.
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.
