Houston’s October Heat Nears Record as Brief Cooldown Arrives Tuesday

Seasonal patterns point to a stubborn, heat-driven drought.

Overview

  • Houston’s official site at Bush Intercontinental has logged 13 days at or above 90 degrees this month, placing October within reach of last year’s record of 18 such days.
  • KTRK reports at least 14 90-degree days citywide this month, reflecting differing counts by location, while both outlets note the unusually late-season heat.
  • A weak cold front is due Tuesday evening, with highs falling to the lower 80s on Wednesday before temperatures rebound late week.
  • Forecasters say up to three additional 90-degree days are possible by week’s end, with increasing rain chances of roughly 30% to 40% into the weekend.
  • Houston has had no measurable rain since Sept. 24, drought is worsening across southeast Texas, Climate Central links faster-onset drought to heat, and a likely weak La Niña favors continued warmth and dryness into November.
