Plano, Texas, located in the humid subtropical climate of North Texas, experiences a long and intense allergy season driven by mild winters, hot summers, and abundant native vegetation.
The year often opens with one of the region's most notorious allergens: mountain cedar (Ashe juniper), which peaks from December through February and triggers the infamous "cedar fever." As winter fades, tree pollen surges from February through May, with oak, ash, elm, pecan, mulberry, and cottonwood producing heavy airborne loads—oak being particularly aggressive in April.
Grass pollen takes over from late April through September, dominated by Bermuda, Johnson, Timothy, and Kentucky bluegrass, thriving in the region's warm, humid conditions. Fall brings a sharp rise in weed pollen from August through November, with ragweed as the primary offender, alongside pigweed, lamb's quarters, and careless weed. Overlaps between late-season grasses and early fall weeds often intensify symptoms in September.
Beyond pollen, Plano residents contend with year-round mold spores fueled by humidity and decaying vegetation, along with dust mites, elevated ozone levels in summer, and occasional dust transported by southerly winds.
Overall, Plano's allergy profile is defined by a nearly continuous calendar of exposure, with cedar, oak, Bermuda grass, and ragweed as its defining triggers.
