Houston, TX – Residents across southeast Texas are under an Air Quality Alert today, Friday, September 12, 2025, as the National Weather Service (NWS) warns of ozone pollution levels reaching unhealthy ranges for sensitive groups.
According to the NWS Houston/Galveston office, atmospheric conditions are favorable for high ozone production across Houston, Galveston, and surrounding counties. The alert is in effect through this evening, with health officials urging people—especially children, older adults, and those with respiratory conditions—to limit strenuous outdoor activity during the hottest parts of the day.
Friday’s forecast calls for high temperatures near 95°F across Houston and much of southeast Texas, with little chance of rain. Extended outlooks show the heat will persist through next week, with only a 10–20% chance of isolated showers. In Galveston, slightly cooler highs near 88°F are expected, but warm overnight lows in the upper 70s and 80s will keep humidity levels elevated.
To help reduce ozone pollution, officials are asking residents to limit driving, carpool when possible, and refuel vehicles in the evening hours. Outdoor activities should be scheduled for early morning or after sunset when ozone levels typically decline.
The NWS noted this is one of several ozone alerts issued this summer, as stagnant air and above-average heat continue to impact air quality in southeast Texas.
