West Palm Beach, FL Pollen Levels Today

West Palm Beach sits in a humid subtropical zone where warm temperatures, abundant rainfall, and a long growing season create a nearly year-round allergy environment.

Tree pollen typically launches the heaviest season, beginning as early as late December and peaking from February through April. Oak is the dominant offender, joined by bayberry, Australian pine, cedar/juniper, pine, and melaleuca, with palm species and Brazilian pepper adding to the load.

As tree pollen tapers, grass pollen rises and remains problematic from late spring well into summer and early fall, driven by Bahia, Bermuda, and St. Augustine grasses that thrive in South Florida lawns and pastures.

Weed pollen becomes more prominent in late summer and fall, with ragweed, pigweed, dog fennel, and sagebrush leading the mix through October.

Because seasons overlap considerably—grasses can pollinate alongside lingering trees in spring and early weeds in late summer—symptom flare-ups often intensify during these transitions.

Non-pollen triggers are especially significant here: persistent humidity fuels high outdoor and indoor mold counts (notably Cladosporium and Alternaria), while dust mites flourish year-round, and coastal air quality can be affected by Saharan dust events.

Overall, West Palm Beach's allergy profile is defined by extended pollen seasons, heavy grass exposure, and consistently elevated mold pressure.
