Air Quality Alert: Houston-Galveston-Brazoria Area Reaches Unhealthy Levels for Sensitive Groups

Current Air Quality

In the Houston-Galveston-Brazoria reporting area of Texas, air quality observations for February 24, 2026, indicate varying levels of pollutants. The primary concern is fine particulate matter (PM2.5), which reached an Air Quality Index (AQI) of 129, placing it in the “Unhealthy for Sensitive Groups” category. Ozone (O3) levels remained in the “Good” category with an AQI of 36.

What This Means

An AQI level of 129 for PM2.5 is classified by the EPA as Unhealthy for Sensitive Groups. This indicates that while the general public is less likely to be affected, members of sensitive groups may experience health effects from breathing the air. The higher the AQI value, the greater the level of air pollution and the greater the health concern.

Who Should Take Precautions

Sensitive groups for fine particulate matter include people with heart or lung disease, older adults, children, and teenagers. These individuals are at a significantly higher risk of experiencing adverse health effects when PM2.5 levels are elevated.

What You Should Do

Members of sensitive groups should consider reducing prolonged or heavy exertion outdoors. It is recommended to take more breaks and engage in less intense activities. If you are in a sensitive group, watch for symptoms such as coughing or shortness of breath. The general public is generally not affected at this AQI level.
