National Weather Service observations at Houston Hobby Airport (KHOU) recorded a maximum temperature of 70°F on April 19, 2026, peaking around 3:45–3:50 PM local time amid overcast skies and residual moisture from prior rainfall, which capped daytime heating well below the April climatological normal of 80°F. This precise measurement from official hourly data aligns with trader consensus, reflecting aggregated real-money bets on forecast models like GFS and ECMWF that anticipated suppressed highs in the low 70s due to persistent cloud cover and cool easterly winds. With resolution imminent via verified airport records, challenges would require an unprecedented data correction by NOAA archivists, though historical precedents show such revisions are exceedingly rare for settled daily maxima. Upcoming NWS climatological reports will finalize the record, but current evidence solidifies the outcome.
