Fort Lauderdale, FL Pollen Levels Today

Fort Lauderdale's subtropical coastal climate creates a nearly year-round allergy season, with warm temperatures, high humidity, and mild winters that prevent the hard freezes that typically suppress pollen production in other regions.

Tree pollen is the earliest major trigger, ramping up from late December through April, with oak, cedar, Australian pine, palm, bayberry, and melaleuca among the most significant local contributors. As tree pollen wanes, grass pollen takes over and remains problematic from late spring through summer and often well into fall, driven by Bahia, Bermuda, and St. Augustine grasses that thrive in South Florida lawns.

Weed pollen becomes prominent in late summer and fall, with ragweed, pigweed, dog fennel, and sagebrush leading the way; because Florida's growing season is so extended, it's common for lingering grass pollen to overlap with early weed pollen, intensifying symptoms from August through October.

Beyond pollen, the region's persistent humidity fuels heavy outdoor and indoor mold growth year-round, while dust mites flourish in humid homes, and coastal ozone and vehicle emissions can worsen symptoms.

Overall, Fort Lauderdale's allergy profile is defined by extended pollen seasons, significant seasonal overlap, and a consistently high mold and humidity burden that affects sufferers throughout the year.
