When Is South Dakota Allergy Season?

As a midwestern state, South Dakota experiences just about every season in its entirety, meaning you get hot summers, moderate falls and springs, and cold winters. This makes allergy season fairly typical, beginning in early spring and going until the first frost of winter.

Allergens by Season

Let’s take a look at some of the allergens that are common to South Dakota’s seasons.


Summer is grass allergy season for South Dakota. The season usually starts in May and goes into July. Summer grass allergies in South Dakota may include bluegrass, ryegrass, timothy, Johnson, redtop, orchard, Bermuda, and fescue grass pollen.


In fall, weed allergies are the most common. The weed allergies in South Dakota usually include ragweed, sagebrush, dock, marsh elder, Russian thistle, and pigweed.


South Dakota gets plenty cold in winter, saving allergy sufferers from pollen allergies for a while. However, indoor allergens like dust mites, mold, and pet dander will still be a concern.


South Dakota has an abundance of trees thanks to its wilderness, like the Black Hills National Forest. In spring, tree allergies are at their worst, with the culprits including ash, elm, birch, maple, oak, and willow.

Common Allergens

South Dakota residents can expect many of the same allergens the rest of the country experiences. This means seasonal tree, weed, and grass pollen allergies and indoor allergies such as dust mites, mold, and pet dander year-round.

Common Symptoms

South Dakota 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.

Testing and Diagnosis

With so much pollen in the air throughout allergy season and with indoor allergies being year-round, it can be almost impossible to identify the specific source of your allergies. With an allergy test, you can learn your primary allergens. Wyndly makes allergy testing easy with our at-home allergy tests. Order your at-home test from Wyndly today!

Let’s look into 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.

Modern and Efficient At-Home Method

  1. Order 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 personalized treatment plan. Our doctor will interpret your results, create an allergy profile, and walk you through a treatment plan.

Treatment and Remedies

Allergies can affect your daily life or just cause general discomfort. Fortunately, there are plenty of ways to manage and even treat your allergy symptoms. There are several methods you may want to try.

Limiting Exposure

Limiting your exposure is a good first step in managing your allergy symptoms. Airborne allergies can be difficult to avoid, but certain measures can help.

  • Check the pollen count: It’s a good idea to check the pollen count when you wake up in the morning. This will give you an idea of how bad your allergies might be that day. If pollen levels are high, try to stay indoors as much as possible. If you do go outside, wearing a mask, hat, and sunglasses can help keep exposure to a minimum.
  • Trim tree branches, pull weeds, and cut grass: It might not make a huge difference, but trimming tree branches, getting rid of weeds, and keeping grass short can help reduce the amount of pollen they produce, which can reduce pollen levels around your home.
  • Keep the house clean: Take care to keep your house extra clean during allergy season. Vacuuming with a HEPA filter vacuum and dusting with a wet rag are both good ways to get rid of pollen.
  • Take shoes off: When you get home, removing your shoes can keep you from tracking in extra pollen.
  • Wipe off pets: When your pets come inside, be sure to wipe off their paws and fur with a towel. This will ensure they don’t track in too much pollen either.
  • Shower after being outside: After being outside, it’s a good idea to rinse pollen off your skin and hair. If you don’t have the time or energy for a shower, washing your hands and face can help too.


Although limiting exposure may be effective for some people, many more will need additional help from allergy medications. There are a wide variety of over-the-counter options such as antihistamines, nasal sprays, eye drops, and decongestants.

Sublingual Immunotherapy

If you’re looking for long-term allergy relief and treatment, sublingual immunotherapy is the best option. Sublingual immunotherapy doesn’t just manage your symptoms, it addresses them at their source, providing long-term allergy relief. When you use sublingual immunotherapy, your immune system is retrained to ignore allergy substances instead of triggering an allergic response. This is done through small, gradually increasing doses of your allergen.

Allergy shots can be painful and require a visit to the doctor for each dose. Sublingual immunotherapy is painless and can be self-administered at home.
