Allergy is Low in Dallas, College Station, Waco, and Abilene, Moderate in El Paso, Denton, and Lubbock, and High in Houston, San Antonio, and Austin.
Allergy risk levels are based on pollen counts, mold spore measurements, and air quality data from monitoring stations. The index reflects the combined burden of tree, grass, and weed pollen along with indoor/outdoor mold activity.
Data is updated daily during high-pollen seasons and every 2–3 days during winter months.
