Recent National Weather Service and AccuWeather guidance points to sunny skies and high pressure over southeast Texas, supporting afternoon highs in the mid-to-upper 90s for Houston on August 17. Model consensus shows limited moisture and light southeast winds, with the European model favoring peaks near 98°F while the GFS trends slightly warmer toward 99–100°F. Historical August climatology for the region centers on 93–95°F averages, so current conditions reflect above-normal ridging that has already produced several near-100°F days this month. Traders appear to weigh these factors against minor uncertainties in daytime heating and any late-day sea-breeze effects, keeping the two leading temperature bins closely matched ahead of the final observation.

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 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 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.
