Carrollton, TX, sits within the humid subtropical climate of the Dallas-Fort Worth metroplex, an area notorious for one of the most demanding allergy profiles in the country. Mild winters, hot summers, and a long growing season mean residents contend with overlapping pollen seasons nearly year-round.
The cycle begins with a particularly aggressive tree pollen season from late December through April, led by mountain cedar (Ashe juniper) in winter, followed by oak, elm, ash, pecan, cottonwood, and mulberry in early spring—oak typically producing the heaviest local load in March and April.
As tree pollen tapers, grass pollen rises from late April through summer, with Bermuda, Johnson, Timothy, and ryegrass dominating and often lingering into early fall due to Texas's extended warm season.
Weed pollen takes over from August through November, driven heavily by ragweed, along with pigweed, careless weed, sagebrush, and lamb's quarters. Spring tree-grass overlap and late-summer grass-weed overlap frequently intensify symptoms.
Beyond pollen, Carrollton's humidity fosters persistent outdoor and indoor mold (especially Alternaria and Cladosporium), while dust, high ozone levels, and periodic wind-blown particulates from drier regions add year-round irritants.
Overall, Carrollton's allergy profile is defined by prolonged, overlapping seasons and a strong mold and ragweed presence.
