Official measurements from National Weather Service stations, including Houston Hobby Airport, recorded a daily maximum of 94–95°F on September 15, 2026, under mostly clear skies with light southeast winds and high humidity that produced heat indices near 107°F. This outcome aligned with model consensus from prior days showing mid-90s highs amid a persistent warm, moist airmass, exceeding the September normal of about 89°F but falling short of record territory. Trader consensus at near-100% on that bin reflects verification against these authoritative observations rather than forecasts. Shifts in station selection, post-analysis quality control revisions, or differing definitions of “Houston” boundaries could theoretically alter the final figure, though such adjustments are uncommon for daily maxima.

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.
