Latest National Weather Service forecasts for Houston on September 13 project a daytime high of 93–94°F under mostly sunny skies with a 30–40% chance of afternoon showers and thunderstorms, driven by southerly flow and high humidity typical of late-summer Gulf moisture. This consensus from official models positions the 92–93°F and 94–95°F bins as the leading market-implied outcomes at 46.5% and 31.5%, respectively, reflecting trader assessment of limited cooling potential and heat-index values near 105°F. Historical September averages near 90°F provide context, but current steering patterns and absence of tropical influences support the elevated range. Updated model runs and evening observations ahead of resolution will refine probabilities as conditions evolve.

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 13 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.Latest National Weather Service forecasts for Houston on September 13 project a daytime high of 93–94°F under mostly sunny skies with a 30–40% chance of afternoon showers and thunderstorms, driven by southerly flow and high humidity typical of late-summer Gulf moisture.
