Official National Weather Service observations from Austin Bergstrom Airport recorded a daily maximum of 76°F on October 4, 2026, reached at 3:59 PM CDT under overcast skies with light rain and northerly winds. This verified measurement, issued in the agency’s climatological summary, aligns with real-time model guidance and surface data showing suppressed afternoon temperatures roughly 10°F below seasonal normals due to persistent cloud cover and modest precipitation. Trader consensus has converged on the 76-77°F bin at near-certainty levels because the outcome rests on authoritative station data rather than forecasts. Minor station-to-station variations or post-hoc quality-control adjustments remain the only realistic avenues for deviation, though historical precedent indicates such revisions rarely exceed 1°F for this site.
