When Is Wyoming Allergy Season?

Wyoming has a fairly typical allergy season, thanks to cold weather in the winter and mild climates throughout the rest of the year. Typically, residents can expect allergies to start in early March and go until the first frost of winter, which will usually happen sometime around late November.

Allergens by Season

Wyoming has cold winters, which means spring, summer, and fall are the worst times for pollen allergies. Let’s take a look at Wyoming allergies by season.


Summer is Wyoming’s grass allergy season. This season will usually start in May and go into early to late July. The grass allergies in Wyoming are usually from bluegrass and bent, timothy, and fescue grasses.


Fall marks weed allergy season in Wyoming. This season usually begins in late August and goes until the first frost of winter. Fall allergies are typically due to ragweed, smotherweed, sagebrush, wormwood, orache, and amaranth.


Winter in Wyoming can get very cold, preventing most plants from producing pollen. Indoor allergens like dust mites and pet dander may still be a concern during the colder months.


Spring allergies in Wyoming can usually be attributed to tree pollen. This season can start as early as February and go into the late spring and early summer months. The trees that cause the most allergies in Wyoming include aspen, poplar, cottonwood, willow, ash, juniper, boxelder, birch, and maple.

Common Allergens

Wyoming has many of the same seasonal allergies as other states, with tree, grass, and weed pollen being the primary culprits. Indoor allergens like mold and dust mites can also contribute to allergies.

Common Symptoms

Wyoming 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

Finding the source of your allergies is important, but it can sometimes be difficult to do. This is because many plants will produce pollen throughout allergy season, making it hard to pinpoint which specific pollen is causing your symptoms. Indoor allergies can be year-round, so it’s possible that your symptoms aren’t from pollen. To find out what you’re allergic to, it’s best to take an allergy test. Wyndly offers very convenient allergy tests that you can take at home. These at-home tests just use a finger prick instead of the uncomfortable test you take at the doctor’s office. Order your at-home allergy test today.

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. 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 your personalized treatment plan.

Treatment and Remedies

Allergy symptoms may be miserable, but they’re fortunately very manageable and even treatable in some cases. The following are some methods and remedies that may work for you.

Limiting Exposure

The first thing many allergy sufferers try is limiting their exposure to their allergens. When you’re allergic to pollen, it’s hard to avoid it completely, but you can make sure that the amount you breathe in is kept to a minimum by taking the following measures.

  • Mask up and protect your eyes: When you go outside during allergy season, you can reduce the pollen that gets in your eyes and airways by wearing an N95 mask and sunglasses.
  • Watch the pollen count: The pollen count tells you how high the concentration of pollen in the air is on that day. If the pollen count is high, consider staying indoors as much as you can.
  • Watch out for morning hours: Pollen levels tend to peak in the morning and early afternoon, so it’s best to limit outdoor time to the evenings if possible.
  • Keep your home clean: If you want to reduce pollen levels in your home, make sure to clean it more frequently during allergy season. Using a HEPA filter vacuum and dusting hard surfaces with a wet rag is a good idea.
  • Wash your clothes: Do laundry more often during allergy season to get pollen off your clothes, and avoid line drying your clothes outside.
  • Shower more frequently: Pollen can also stick to your hair and skin, so be sure to rinse off after being outside. You should at least wash your hands and face well if you can’t shower right away.


It’s very possible that limiting your exposure won’t be enough to manage your symptoms. In that case, over-the-counter allergy medications may be a route you want to try. The most common options are antihistamines, nasal sprays, eye drops, and decongestants. If none of those are working, you can also consult your doctor about prescription options as a last resort.

Sublingual Immunotherapy

If you’d rather treat your symptoms instead of just managing them, you may want to consider sublingual immunotherapy. Sublingual immunotherapy is a treatment that retrains your immune system to ignore the allergens that cause your allergies. This works by introducing small, gradually increasing doses of allergens to your system. Sublingual immunotherapy is taken by mouth and can be done in the comfort of your home. Using sublingual immunotherapy, you can find long-term relief from your allergy symptoms.
