Wisconsin is one of the better states for those with seasonal allergies, but that doesn’t mean that it’s completely free of allergy issues. The mild climate and extremely cold winters can provide a longer respite from allergies than other states get, but spring, summer, and fall can still cause sneezing, itchy eyes, and other unpleasant symptoms for Wisconsinites.

Even if seasonal allergies aren’t as bad, it’s important to keep in mind that indoor allergens like dust, mold, and pet dander will be present all year. With that being said, what seasonal allergies should you be aware of if you’re a Wisconsin resident? What can you do to mitigate allergy symptoms?

You can count on Wyndly to help. With a personalized allergy treatment plan, you can get long-term relief from your Wisconsin allergies. Sign up for your personalized allergy consultation today, or read on to learn more about Wisconsin’s allergy season.

When Is Wisconsin Allergy Season?

Wisconsin allergy season is a little shorter than in most other states. The long, cold winters mean that you likely won’t have to worry about spring allergies until at least late February. Sometimes the season may not start until March or later. Allergy season will typically end after the first frost.

Allergens by Season

Spring, summer, and fall are the primary allergy seasons in Wisconsin, and these are the allergens that are most prominent for each season.


Summer is grass allergy season for Wisconsin. Grass allergy season will usually begin in May and stick around into July. The worst grass allergies will be due to ryegrass and timothy, fescue, orchard, and bentgrasses.


Next we have weed allergies in the fall. Fall allergies usually begin in late August and go until the first frost in winter. The main weed allergies will be a result of ragweed, wormwood, orache, and sagebrush pollen.


Winter in Wisconsin should provide you with a nice, long break from seasonal allergies. Indoors allergies will still be a problem in winter, though, so watch out for symptoms from dust, pet dander, mold, and cockroaches.


Spring allergies in Wisconsin will begin when the weather starts to warm up. Sometimes this won’t be until March. Tree pollen will be the main issue in spring, with hickory, walnut, ash, maple, willow, oak, and mulberry being the main contributors to allergy symptoms.

Common Allergens

Wisconsin has the same issues with tree, grass, and weed allergies that the rest of the country does. Indoor allergies are an issue for residents as well.

Common Symptoms

Wisconsin residents can expect the following allergy symptoms:

  • Runny nose
  • Coughing
  • Congestion
  • Sneezing
  • Headaches
  • Scratchy throat
  • Itchy eyes
  • Watery eyes
  • Hives
  • Aggravated asthma symptoms

As always, reactions will vary from person to person, but in general, allergies will cause one or more of these symptoms to occur.

Allergens Around the State

Though a variety of allergens can be found throughout Wisconsin, some areas will have allergens that are specific to that county. Let’s look at some of the biggest areas of Wisconsin and the allergens that they have.


In the Superior/Marinette/Rhinelander area, the chief spring allergies are ash, oak, maple, and willow tree pollen. In summer, bent, timothy, and orchard grass pollen is the primary issue. Fall’s weed allergy season includes ragweed, wormwood, orache, and sagebrush.

The Eau Claire/La Crosse area spring allergy season includes hickory, maple, ash, oak, and willow tree pollen. Summer allergies are primarily from bent and timothy grass pollen. Fall allergies will be to ragweed, mustard, wormwood, amaranth, and sagebrush pollen.

Testing and Diagnosis

If you’re unable to pinpoint the cause of your allergies, you’re not the only one. There is so much pollen in the air during allergy season that it can be hard to figure out which plant is causing your issues. However, an allergy test can easily show you what your primary allergies are and reveal allergies you may not have even considered. An at-home test from Wyndly makes things even easier. You can get it delivered straight to your door and get it done with a simple finger prick. Buy your allergy test from Wyndly today to find out more about your allergies.

Here’s 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 pain by getting an at-home test.

Modern and Efficient At-Home Method

  1. Get Wyndly’s at-home allergy test. We ship our CLIA-certified test straight to your door.
  2. Take the allergy test and send it back to us. Just do a quick finger prick test to provide us with a blood sample and mail it back when you’re done.
  3. Receive your personal allergy profile. Our doctor will interpret your results, create an allergy profile, and walk you through a treatment plan.

Treatment and Remedies

Allergies can be miserable, but there are various treatments and remedies to help you deal with your symptoms. Let’s take a look at some of these methods.

Limiting Exposure

Limiting exposure can be a good start for managing your allergy symptoms. While avoiding pollen altogether is nearly impossible, there are ways to keep your exposure to a minimum.

  • Check the pollen count with an app: Using an app or website to check the pollen count can ensure you’re prepared for high-pollen days. You can avoid going outdoors if possible, and you can mask up when you do have to go outside.
  • Cut grass and trim trees: Cutting the grass and trimming the tree branches in your yard can reduce the amount of pollen they produce. It’s best to have someone else do this for you if you can.
  • Clean your home: There are various ways to keep your home clean and as free from pollen as possible. Vacuuming with a HEPA filter vacuum and dusting can help. It’s also a good idea to put a HEPA filter on your A/C system.
  • Wash your hair, body, and clothes: Pollen is light and sticky, so it’s inevitably going to get on your skin, clothes, and in your hair. Make sure to shower more frequently and do laundry often during allergy season.
  • Wipe pets down: When your pets come inside, it’s a good idea to wipe them off with a towel to get as much pollen off them as you can.


Limiting exposure doesn’t work for everyone, so you may want to try over-the-counter allergy medications next. The most common and effective options are antihistamines, nasal sprays, decongestants, and eye drops. You may want to consult your doctor about prescription options if OTC isn’t working. Medications can help relieve your allergy symptoms for short-term relief, but they aren’t a long-term solution.

Sublingual Immunotherapy Allergy Drops

Limiting your exposure and taking allergy medications might help with your symptoms, but they can’t help the root cause of your allergies, an overreactive immune system. If you’re looking for long-term or lifelong relief from your allergies, sublingual immunotherapy allergy drops may be for you. Allergy drops introduce small amounts of your allergen to your system in gradually increasing amounts over time. This teaches your immune system to naturally ignore these triggers instead of having an allergic response.
