Houston, TX – A spring heat surge across Southeast Texas is triggering an Ozone Action Day, with health officials warning of poor air quality through Tuesday evening.
According to the National Weather Service in Houston/Galveston, temperatures are expected to reach the upper 80s and low 90s in cities including Houston, Conroe, Wharton, and College Station. The warm, stagnant conditions are conducive to elevated ozone pollution, prompting an air quality alert for sensitive groups.
The alert, in effect until Tuesday night, March 25, 2025, affects urban centers and surrounding counties, including Liberty, Galveston, Brazoria, and Montgomery. Residents with respiratory issues, particularly children and the elderly, are urged to limit outdoor activity during the afternoon and early evening hours when ozone levels peak.
Transportation officials recommend carpooling or using public transit to reduce emissions, while health experts suggest scheduling exercise during early morning or later in the evening.
While Southeast Texas often experiences ozone alerts during warmer months, these March temperatures—reaching 90°F in places like Livingston, Edna, and Columbus—are above average.
