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 30 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the William P. Hobby Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Official observations from the National Weather Service at William P. Hobby Airport (KHOU)—the market's designated resolution source—confirm Houston's maximum temperature on April 30 reached 88-89°F, yielding Polymarket's 100% trader consensus on this outcome backed by real-money positions. Persistent cloud cover and scattered showers, as detailed in NWS Houston-Galveston advisories, curtailed solar insolation and daytime heating despite a humid southerly airflow and near-record potential in the warm air mass. This matches pre-event forecast consensus from NOAA models like HRRR, which projected capped highs amid precipitation risks. Realistic challenges are minimal but could involve rare post-processing revisions to quality-controlled data or disputes over peak-hour sensor readings; final NWS climatological summary expected soon will solidify resolution.
