El Paso, TX Pollen Levels Today

El Paso's position in the Chihuahuan Desert, combined with its arid climate, high winds, and mild winters, creates a uniquely prolonged and intense allergy season that often extends nearly year-round.

Tree pollen kicks off early, with mountain cedar and juniper releasing significant pollen from December through February, followed by mulberry, ash, cottonwood, elm, oak, and pecan from March into May. Mulberry has historically been so problematic that the city banned new plantings decades ago, though mature trees remain a major springtime trigger.

Grass pollen overlaps with late tree season and dominates from May through July, with Bermuda grass being the chief offender, alongside Johnson grass and various range grasses thriving in the region's irrigated areas.

Weed season runs heavy from late summer through the first frost, driven by careless weed, tumbleweed (Russian thistle), pigweed, sagebrush, and ragweed, typically peaking in September and October. The overlap between lingering grasses and emerging weeds in August often intensifies symptoms.

Beyond pollen, El Paso's dry, dusty environment produces frequent windblown dust and sand, elevated outdoor mold spores after monsoon rains, and cross-border air pollution that aggravates airways.

Overall, El Paso's allergy profile is defined by desert vegetation, persistent wind, dust, and a remarkably extended pollen calendar.
