Official measurements from Houston-area stations, including those aligned with NOAA and local airport data, recorded a daily high of 94–95°F on August 18, 2026, under a strong heat dome that produced upper-90s conditions with minimal cloud cover and low precipitation. This outcome aligns with climatological norms for mid-August in southeast Texas, where average highs near 95°F are common, and recent model runs showed limited deviation from those baselines. Trader consensus at near-100% reflects verified observational data rather than forecasts, with negligible probability assigned to adjacent bins due to the absence of measurement revisions or station discrepancies. A sudden official correction or alternative station reading outside this narrow range remains the only realistic pathway to alter the result before final settlement.

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 18 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.
