Tampa, FL Pollen Levels Today

Tampa's subtropical climate along Florida's Gulf Coast creates a uniquely prolonged and intense allergy season, with warm temperatures, high humidity, and mild winters allowing pollen production for much of the year.

Tree pollen arrives early and hits hardest, typically beginning in late December and peaking from February through April. Dominant culprits include oak, which blankets the region in yellow dust, along with cedar, juniper, pine, bayberry, and cypress.

As tree pollen tapers, grass pollen takes over from April through October, an unusually long window driven by the warm climate; Bahia, Bermuda, and Johnson grasses are the primary offenders, with peaks in late spring and summer.

Weed pollen builds in late summer and dominates the fall, with ragweed leading the charge from August through November, accompanied by pigweed, dog fennel, and sagebrush. Overlap is significant—grass and weed seasons routinely collide in August and September, often intensifying symptoms.

Beyond pollen, Tampa's persistent humidity fuels year-round outdoor and indoor mold, including Alternaria and Cladosporium, while dust mites thrive in humid homes. Coastal air quality and occasional Saharan dust events can add further irritation.

Overall, Tampa's allergy profile is defined by an extended, overlapping season dominated by oak, Bahia grass, ragweed, and persistent mold.
