Miami’s subtropical climate means allergy season never fully stops. Tree pollen peaks roughly February to May, and Bermuda grass can pollinate year-round (UF/IFAS).
Today’s top pollen: Weed pollen, low (2 of 5). 5-day forecast (includes pollen data from Google)

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
- Melaleuca, oak and pine pollen can travel miles in dense urban areas (UF/IFAS); keep windows closed on windy days.
- Year-round humidity favors mold indoors too; keep A/C running and fix leaks quickly.
- 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?)
See the NeilMed Sinus Rinse kit on AmazonDust-mite pillow & mattress covers
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 Miami?
Tree pollen peaks roughly February to May, and grass pollen can linger nearly year-round, so many people have some symptoms in every season.
Why do I have allergies all year in Miami?
Subtropical South Florida has overlapping seasons, and grasses like Bermuda can pollinate year-round, so there’s rarely a pollen-free month (UF/IFAS).
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 Miami?
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).
