McKinney, Texas, sits in the humid subtropical climate zone of North Texas, where mild winters, warm springs, and long growing seasons create a year-round allergy challenge with few true breaks between pollen cycles.
The allergy calendar begins aggressively in winter with the region's notorious mountain cedar (Ashe juniper) season from December through February, followed by a heavy spring tree pollen surge from oak, pecan, ash, elm, mulberry, and cottonwood peaking from March through April.
As tree pollen tapers, grass pollen takes over from late April into summer, dominated by Bermuda, Johnson, Timothy, and Kentucky bluegrass, with peaks typically in May and June.
By late August, weed pollen ramps up, led by ragweed—which thrives across North Texas fields and roadsides—along with pigweed, sagebrush, and lamb's quarters, continuing through October's first hard freeze. Overlap between late-season grasses and early fall weeds often intensifies symptoms in August and September.
Beyond pollen, McKinney residents contend with high year-round mold spore counts fueled by humidity and periodic heavy rains, persistent dust carried by North Texas winds, and elevated ozone during hot summer months.
Overall, McKinney's allergy profile is defined by early cedar, robust spring trees, and stubborn ragweed, with mold and dust compounding symptoms nearly year-round.
