Naples has a subtropical pollen year: tree pollen peaks around February to May, and grasses and mold can linger through much of the year.

Main Pollen Triggers
Trees
- Oak – still a leading allergen, peaking February–May in South Florida (UF/IFAS).
- Melaleuca and pine – UF/IFAS notes these produce lightweight pollen that travels miles in South Florida urban areas.
- Australian pine (casuarina) – an invasive tree with highly allergenic pollen (UF/IFAS).
- Wax myrtle – a highly allergenic native shrub.
Grasses
- Bahiagrass and Bermudagrass – Bermudagrass can pollinate year-round in subtropical South Florida (UF/IFAS), so grass allergies may never fully take a break.
Weeds
- Ragweed – the most clinically significant weed, rising in late summer and fall.
- Dog fennel and pigweed – other highly allergenic weeds; goldenrod is often blamed but its sticky pollen doesn’t travel well on the wind (UF/IFAS).
Mold
Florida’s hot, humid wet season (roughly late spring through early fall, per NOAA climate summaries) favors outdoor mold, which triggers symptoms similar to pollen.
Local Tips
- Winter visitors often arrive right as tree season builds; start any doctor-recommended allergy medicine before symptoms peak.
- Choose lower-allergen landscaping; UF/IFAS lists options such as female gumbo-limbo.
- Keep windows closed and run the A/C with a good filter during high-count days (UF Health).
- Shower and change clothes after time outdoors; dry laundry in the dryer, not outside (UF/IFAS).
- Rain washes pollen out of the air, so counts often drop after a storm; hot, dry, windy days push counts up (UF Health).
- Check daily counts from an AAAAI National Allergy Bureau station or local forecast.
When to See an Allergist
ACAAI suggests seeing an allergist when symptoms last for months, interfere with sleep, work or school, aren’t controlled by over-the-counter medicines, or come with asthma symptoms such as wheezing or shortness of breath. An allergist can test which Florida pollens you react to and discuss immunotherapy. Trouble breathing or swelling of the face or throat is an emergency – see seasonal allergy emergencies.

HEPA air purifier & filters
A portable HEPA purifier sized to the room can lower airborne particles such as pollen and dust; it only works if you replace filters on schedule. (EPA: Guide to Air Cleaners in the Home)
See the Levoit Core 300 on AmazonSaline nasal rinse kit
Rinsing with saline can clear pollen from the nose; use distilled, sterile or boiled-then-cooled water, never plain tap water. (FDA: Is rinsing your sinuses with neti pots safe?)

Allergists recommend zippered, allergen-proof encasings for pillows, mattresses and box springs, plus hot-water washing of bedding. (ACAAI: Dust Allergy)

When is allergy season in Naples?
Tree pollen peaks roughly February to May, and grass pollen can linger nearly year-round, so many people have some symptoms in every season.
Do snowbirds get allergies in Naples?
Yes. Many winter residents arrive during peak tree season and can develop new sensitivities to Florida plants over a few seasons.
Where can I check today’s pollen count?
Use the AAAAI National Allergy Bureau station map for certified counts, or a local weather forecast. Counts change daily with wind and rain.
When should I see an allergist in Naples?
If symptoms last for months, disrupt sleep or work, don’t respond to over-the-counter medicines, or come with wheezing, a board-certified allergist can test which local pollens you react to and discuss treatment (ACAAI).
