Official measurements from Houston Hobby Airport, the primary station for local climatological reports, recorded a daily maximum of 91°F on September 9, 2026, at 2:59 PM CDT—precisely within the 90-91°F bin that now carries full market-implied probability. This outcome aligns with near-normal conditions for the date, where the 1991-2020 average high is 90.5°F, and reflects limited afternoon heating amid typical late-summer humidity and partial cloud cover rather than extreme clear-sky radiation. National Weather Service data confirm no higher reading occurred, locking trader consensus around verified observations. Resolution could face challenge only from alternate station data or post-event quality-control revisions, though such adjustments remain rare for this airport site.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the William P. Hobby Airport Station in degrees Fahrenheit on 9 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=khou
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.Official measurements from Houston Hobby Airport, the primary station for local climatological reports, recorded a daily maximum of 91°F on September 9, 2026, at 2:59 PM CDT—precisely within the 90-91°F bin that now carries full market-implied probability.
