Austin sits at the edge of the Texas Hill Country, where a warm, humid subtropical climate and mild winters create one of the longest and most intense allergy seasons in the United States. The city's defining allergen is mountain cedar (Ashe juniper), which triggers the infamous "cedar fever" from December through February and is unique in its severity here.
As cedar subsides, a broader tree pollen wave takes over from February through April, led by oak (especially live and post oak), elm, ash, pecan, and mulberry, with oak often coating the city in yellow dust. Grass pollen follows, peaking from April through June and lingering into summer, with Bermuda, Johnson, Timothy, and Bahia grasses as the primary offenders.
Weed season arrives in late summer and fall, running August through November, dominated by ragweed, along with pigweed, sagebrush, and careless weed. Overlap between late tree and early grass season in spring, and between grass and weed pollen in late summer, frequently intensifies symptoms.
Beyond pollen, Austin's humidity fuels year-round mold (particularly Alternaria and Cladosporium), while dust, cedar elm debris, and urban ozone add to the load. Overall, Austin's allergy profile is defined by cedar fever, heavy oak pollen, and a nearly year-round exposure cycle.
