Seasonal Allergies in Florida: When Pollen Peaks and How to Get Relief

Written by Naurah Gaspard, DNP, FNP-C, FNP-BC · Medically reviewed by Cherlie Joseph, MSN, FNP-BC · Updated November 2026

In Florida, allergy season can run almost all year. Tree pollen (especially oak) peaks from about February to May, grasses release pollen from spring through fall, and weeds such as ragweed add to it later in the year. A daily steroid nasal spray, started before your worst season, is the most effective single treatment for most adults.

When is allergy season in Florida?

Florida's warm climate gives plants a long growing season, so many people here never get a true break. According to the University of Florida's IFAS extension, Florida trees often release pollen from January to June, and some areas see high oak counts as early as December.

Pollen	Typical Florida timing	Notes
Oak and other trees	Roughly January to June; oak peaks February to May	Oak is a leading spring trigger. Florida has 11 native oak species.
Pine	Late winter and spring	The yellow dust on cars is easy to see, but UF/IFAS notes pine pollen is low-allergenic and often wrongly blamed.
Grasses	Spring, summer and fall	Bermudagrass can pollinate year-round in South Florida.
Weeds, including ragweed	Mostly summer and fall, but possible in any season	Weed pollen is light and travels far on the wind.

Timing shifts from the Panhandle to Miami and from year to year, so a local pollen forecast is more useful than a calendar.

Signs your symptoms are seasonal allergies

Seasonal allergies (allergic rhinitis, or hay fever) happen when your immune system overreacts to pollen. Common signs include:

• Sneezing in bursts, often in the morning or after time outside
• A runny nose with clear, watery mucus
• Itchy nose, eyes, throat or ears
• Watery, red eyes
• Stuffy nose and postnasal drip that can cause a tickly cough
• Feeling tired or foggy, often from poor sleep

Allergies do not cause fever or body aches. If you have those, a virus is more likely. Symptoms that return around the same months each year are a strong clue that pollen is the cause.

Simple ways to cut your pollen exposure

Medicine works better when you also lower the amount of pollen you breathe in:

• Check the daily pollen count and plan yard work or long walks for lower-count days, or after a good rain.
• Keep house and car windows closed and run the air conditioning. Change AC filters on schedule; a higher-efficiency filter can help.
• Shower and change clothes after time outdoors, and wash your hair before bed so pollen doesn't end up on your pillow.
• Wear sunglasses outside to keep pollen out of your eyes.
• Dry laundry indoors during peak season instead of on a line.
• Try a saline rinse to wash pollen out of your nose. Use distilled, sterile or previously boiled and cooled water, never straight tap water.

Treatments that work

Steroid nasal sprays such as fluticasone (Flonase), triamcinolone (Nasacort) and budesonide (Rhinocort) are sold over the counter and treat congestion, sneezing and runny nose. They work best when used every day, and can take several days to reach full effect, so start them a week or two before your usual season.

Non-drowsy antihistamine pills such as cetirizine (Zyrtec), loratadine (Claritin), fexofenadine (Allegra) and levocetirizine (Xyzal) are good for itching and sneezing and can be taken as needed. In 2025 the FDA added a warning that some people get rare but severe itching after stopping cetirizine or levocetirizine they had taken daily for months, so talk with a provider if you plan to take one long term.

Allergy eye drops with ketotifen or olopatadine help itchy, watery eyes.

Allergy shots or tablets (immunotherapy), arranged through an allergist, can reduce sensitivity over years for people whose symptoms are not controlled with medicine.

Montelukast (Singulair) is sometimes prescribed, but it carries an FDA boxed warning about mood and behavior changes and is generally not a first choice for allergies alone.

When to talk to a provider

Consider a visit if over-the-counter options are not controlling your symptoms, you are unsure which medicine is safe with your other conditions (such as high blood pressure, glaucoma, pregnancy or an enlarged prostate), you have asthma that flares with allergy season, or you keep getting sinus infections. If you already have a prescription allergy medicine that works, a refill review can keep you covered through the season.

Frequently asked questions

Why are my allergies so bad in Florida?

Florida's mild winters and long growing season mean trees, grasses and weeds release pollen across much of the year, and the humid climate also supports mold. Many people are allergic to more than one of these, so symptoms can overlap from season to season.

Is the yellow pine pollen what makes me sneeze?

Probably not. The University of Florida notes pine pollen is low-allergenic even though it is very visible. Oak and other tree pollens released at the same time are more likely culprits.

When should I start my allergy medicine?

If your symptoms follow a pattern, starting a daily steroid nasal spray a week or two before your usual season gives it time to work. Follow the label, and ask a provider if you need it most of the year.
