Allergy is Low in Dallas, Denton, Waco, and Abilene, Moderate in El Paso, San Antonio, Austin, College Station, and Lubbock, and Very High in Houston.
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.
