Pollen conditions in Fort Worth are expected to remain similar tomorrow.
Fort Worth sits in North Texas where a humid subtropical climate, mild winters, and prolonged warm seasons create one of the most challenging allergy environments in the United States.
The allergy calendar begins early, with tree pollen surging from late December through April. Mountain cedar (Ashe juniper) triggers the infamous "cedar fever" in January, followed by oak, elm, ash, pecan, mulberry, and cottonwood through spring, when pollen counts frequently reach extreme levels.
As trees taper off in May, grass pollen takes over and persists through summer into early fall, driven primarily by Bermuda, Johnson, Timothy, and Kentucky bluegrass.
By late August, weed pollen dominates, led by ragweed, which is especially prolific across North Texas, alongside pigweed, sagebrush, lamb's quarters, and careless weed through October.
Overlap between late-spring trees and early grasses, as well as between summer grasses and early fall weeds, often intensifies symptoms during transitional months.
Non-pollen triggers are also significant: year-round mold spores thrive in the region's humidity, while dust, cedar elm debris, and elevated ozone from urban traffic add further irritation.
Overall, Fort Worth's allergy profile is defined by near-continuous exposure, with cedar, ragweed, and Bermuda grass standing out as the region's most impactful allergens.
