Houston, TX – Drivers and outdoor workers across Southeast Texas should brace for another warm, hazy start to the week. The Texas Commission on Environmental Quality (TCEQ) has declared an Ozone Action Day for Tuesday, October 7, 2025, covering Houston, Galveston, and Brazoria counties, as weather conditions are ripe for elevated ozone pollution.
According to the National Weather Service in Houston, light winds and clear skies will trap pollutants near the ground, increasing health risks for sensitive groups, including children, seniors, and those with respiratory conditions. Officials advise residents to limit driving, refuel vehicles after sunset, and reduce outdoor activity during afternoon hours when ozone levels peak.
Temperatures will stay unseasonably warm this week, with highs around 91°F Tuesday through Thursday before slightly cooling into the upper 80s by the weekend. Expect mostly sunny skies and calm winds — perfect for early Halloween decorating or pumpkin patch trips, but still too hot for extended midday outdoor work.
By Thursday, October 9, forecasters expect continued clear, dry conditions across Interstate 45 and surrounding metro areas. Long-range outlooks show steady sunshine through Monday, October 13, with no rain in sight — ideal for fall festivals and outdoor events.
Five-Day Forecast for Houston:
- Tuesday: Sunny, high 91°F
- Wednesday: Sunny, high 91°F
- Thursday: Mostly sunny, high 89°F
- Friday: Clear, high 87°F
- Saturday: Bright skies, high 86°F
