Trader consensus on Polymarket has locked in 82-83°F as the highest temperature in Houston on March 25, reflecting near-unanimous agreement from the latest National Weather Service (NWS) forecast and ensemble model runs from NOAA's Global Forecast System (GFS) and European Centre for Medium-Range Weather Forecasts (ECMWF), which project a daytime high of 83°F under a dominant high-pressure ridge promoting clear skies, light southerly winds, and warm air advection. This positioning aligns with climatological norms for late March, where Houston averages mid-70s but sees occasional warm spikes from Gulf moisture. Realistic challenges include an unexpected increase in marine layer clouds or a subtle cold front nudge, potentially capping highs at 81°F or pushing to 84°F, though current soundings and satellite data show low likelihood before resolution via official observations at Houston's George Bush Intercontinental Airport.
