When Is Louisiana Allergy Season?

The Louisiana allergy season can often last a long time, particularly the spring allergy season. Spring allergies can start as early as February if weather conditions are right, and they can last well into May. Some trees may produce pollen even longer. Fall allergies can also last into November due to the mild climate.

Allergens by Season

In Louisiana, allergies will be at their worst during spring, summer, and fall. The mild winters mean that allergy season can start fairly early too. Here are the allergies broken down by season.


Summer is when grass allergies are at their worst in Louisiana. Grass allergies can start in May and will usually linger until July. Common grass allergies include ryegrass and Bermuda, bent, fescue, timothy, corn, and orchard grasses.


Fall weed allergies usually start in late August and go well into November. In Louisiana, the main triggers for weed allergies include ragweed, pigweed, sagebrush, Russian thistle, and marsh elder.


Winter allergies do provide some relief in Louisiana, though it’s usually short-lived. Trees can start pollinating early in February due to the mild climate.


Spring is probably the worst allergy season for Louisiana residents. It tends to begin in February and go until the early summer months. The main trees that set off allergies include elm, cedar, oak, cypress, willow, ash, mulberry, pecan, and maple trees.

Common Allergens

Louisiana has a wide variety of very allergenic trees. Grass and weed allergies are common allergy culprits as well. For indoor allergies, mold and dust mites can be especially problematic due to Louisiana’s high humidity and heat.

  • Coughing

Testing and Diagnosis

It’s not uncommon for allergy sufferers to have trouble finding the source of their allergy symptoms. Since allergy seasons can often overlap, it can be hard to identify which specific pollen is causing your symptoms. It’s also possible that you’re dealing with year-round indoor allergies and attributing them to seasonal allergies. The best way to find out is with an allergy test from Wyndly. Wyndly provides you with a convenient at-home allergy test that just requires a quick prick of the finger. Order your at-home allergy test from Wyndly today.

Let’s take a look at how different allergy testing options work.

Old-Fashioned Method: Skin Prick Test at Your Doctor’s Office

Skin prick testing requires you to go to the doctor to find out your allergen triggers. It’s often uncomfortable, and it takes time out of your day. You’ll go to the doctor’s office, they’ll administer a test where they prick or scrape your skin with a needle tipped with different allergens, and then they’ll observe the areas they pricked for itchiness, redness, or swelling. All in all, it’s not a pleasant experience. Instead, you can save yourself time and discomfort by getting an at-home test.

Treatment and Remedies

Fortunately, allergies are very manageable and can even be treated using the right methods. The following are some options for remedies and treatments.

Limiting Exposure

If you’re trying to manage your allergy symptoms, limiting your exposure to your primary allergens is a good place to start.

  • Watch the pollen count: When pollen levels are high, it’s a good idea to stay inside as much as possible. You can check the pollen count in your local area using an app or a website.
  • Shower more frequently: When you’ve been outside during allergy season, it’s easy to get pollen on your skin and in your hair. Shower to rinse off if you’ve been outside for a while. If a shower isn’t possible, it’s a good idea to wash your hands and face well at the very least.
  • Cut grass, pull weeds, and trim trees: If you want to reduce plant pollen around your home, cutting grass, pulling weeds, and trimming tree branches can help reduce the amount of pollen they produce.
  • Take shoes off: When you get home, be sure to take off your shoes to avoid tracking pollen in.
  • Keep your house clean: Vacuuming once per week with a HEPA filter vacuum and dusting hard surfaces with a wet rag can help reduce pollen in your home.
  • Keep windows closed: During pollen season, you should keep your windows closed to prevent pollen from floating in easily. It’s also a good idea to install a HEPA filter on your A/C.


When limiting your exposure isn’t providing enough relief, you may consider over-the-counter allergy medications. These widely available options are effective at providing short-term relief for most people. You can try antihistamines, nasal sprays, eye drops, or decongestants.

Sublingual Immunotherapy

If you’re hoping for long-term treatment for your allergy symptoms, OTC allergy medications and limiting exposure won’t be the answer. Instead, you should consider sublingual immunotherapy. Sublingual immunotherapy teaches your immune system to ignore the allergens that cause your allergies instead of reacting with symptoms. This works by introducing the substance in small, gradually increasing doses that are administered under the tongue. Unlike allergy shots, sublingual immunotherapy doesn’t involve painful needles and can be taken in the comfort of your own home.
