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 29 Mar '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.National Weather Service guidance from the Houston/Galveston office, updated March 27, forecasts a high near 74°F on March 29 under partly sunny skies, with northeasterly winds at 10-15 mph gusting to 25 mph following cold front passage, limiting daytime heating through enhanced mixing and cooler air advection across southeast Texas. Despite this, Polymarket traders imply 66% odds for 80°F+ via closely matched 80-81°F (35%) and 82-83°F (31%), betting on potential frontal weakening or underforecast warmth amid March's pattern of highs in the low 80s (e.g., 81°F on March 24). Key differentiators include model spread—GFS ensembles sometimes favor deeper mixing for 82°F peaks versus ECMWF cloudier scenarios capping at 80°F—solar insolation, and dewpoint recovery; expect volatility from afternoon 12z/18z updates resolving boundary layer uncertainties before observation.
