Trader consensus on Polymarket closely splits between 84-85°F (41.5%) and 82-83°F (38.0%) for Houston's highest temperature on April 17, driven by the latest National Weather Service Houston/Galveston Area Forecast Discussion projecting mid-to-upper 80s inland under southerly winds and partly cloudy skies, with only 10% precipitation odds. Differentiating factors include sea breeze penetration from Galveston Bay, which could moderate coastal stations like IAH or Hobby by 2-3°F through increased humidity and clouds, versus fuller diurnal heating in clearer scenarios shown in recent GFS and NAM model runs clustering at 84-86°F. Model ensembles reflect this spread, with historical April normals at 79°F providing context for above-average warmth amid a weakening upper ridge. Afternoon updates from NOAA will refine timing of peak heating.

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 17 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.Trader consensus on Polymarket closely splits between 84-85°F (41.5%) and 82-83°F (38.0%) for Houston's highest temperature on April 17, driven by the latest National Weather Service Houston/Galveston Area Forecast Discussion projecting mid-to-upper 80s inland under southerly winds and partly cloudy skies, with only 10% precipitation odds. Differentiating factors include sea breeze penetration from Galveston Bay, which could moderate coastal stations like IAH or Hobby by 2-3°F through increased humidity and clouds, versus fuller diurnal heating in clearer scenarios shown in recent GFS and NAM model runs clustering at 84-86°F. Model ensembles reflect this spread, with historical April normals at 79°F providing context for above-average warmth amid a weakening upper ridge.
