Pollen Count & Forecast for Austin

Austin’s winter allergy season (December-February) is dominated by Ashe Juniper (Juniperus ashei); pollen travels from the Texas Hill Country into the city. Spring (March-May) has high Oak (Quercus) levels; trees are dense near Zilker Park and Barton Creek. Pecan (Carya illinoinensis) and Elm (Ulmus) contribute near Lady Bird Lake. Late summer (August-October) sees high Ragweed (Ambrosia) and Grass (Poaceae) levels along the Colorado River.

Northerly winds carry cedar pollen into urban corridors; high humidity keeps allergens low to the ground. Year-round Mould (Alternaria, Cladosporium) spores are present; counts rise after heavy rains and in damp areas along the Barton Creek Greenbelt.
