Dallas consistently ranks among the most allergy-challenging cities in the United States, owing to its humid subtropical climate, long growing season, and position within North Texas's mix of prairie, cedar brakes, and urban greenery. The allergy calendar begins early and rarely offers a true break.
Winter brings the region's most infamous trigger—Mountain Cedar (Ashe juniper)—which peaks from mid-December through February and can produce staggering pollen counts carried in from the Hill Country. As cedar wanes, spring tree pollen surges from oak, elm, ash, pecan, mulberry, and cottonwood, typically peaking March through April, with oak often producing the highest counts.
Grass pollen follows, dominated by Bermuda, Johnson, and Timothy grasses, running from late April through summer and sometimes lingering into fall due to Dallas's extended warm season. By August, weed pollen takes over, led by ragweed, pigweed, and careless weed, peaking in September and October.
Overlaps between late tree and early grass season, and between grass and weed season, frequently compound symptoms. Beyond pollen, Dallas's humidity fuels year-round mold (especially Alternaria and Cladosporium), while dust, urban ozone, and highway pollution add further irritation.
Overall, Dallas's allergy profile is defined by near-continuous exposure, with cedar, oak, Bermuda grass, and ragweed as its signature triggers.
