What Are Seasonal Allergies?

Seasonal allergies typically refer to allergies that are triggered by pollen. Pollen is only released by plants during certain times of the year, because of this, these allergies typically aren’t year-round. The primary producers of pollen in Arizona are grasses, trees, and weeds.

When Is Allergy Season in Arizona?

Depending on what you are allergic to, you can experience allergy symptoms during any time of year in Arizona. Pollen allergies will primarily flare up in the spring, summer, and fall. But because of Arizona’s dry and warm climate, pollen allergies can still go throughout the winter.

Arizona is in the Intermountain & High Desert and Desert Southwest allergy regions. Each region has slightly different allergens and allergy seasons, so we’ve compiled the region-specific information for allergy season in Arizona.

When Is Arizona Pollen Season?

In Arizona, grass pollen is mainly produced during the summer months. The fall is when weeds primarily produce pollen, but these plants can produce pollen into the winter. Arizona residents will encounter tree pollen in both the winter and spring.

When Does Allergy Season Start?

Arizona allergy season starts in the spring. Because Arizona has a mild winter, seasonal allergies will take place year-round. This is a longer allergy season when compared to most other states. Because Arizona’s allergy season never stops, it can be a worse state for allergy sufferers.

What Months Are Arizona Allergy Season?

In Arizona, you’ll want to keep an eye on pollen counts in April, May, and September. These months are when seasonal allergies are typically at their peak. During these months, try limiting your time outdoors or going out in the evening when pollen counts tend to be lower in Arizona.

If you have seasonal allergies and are traveling to Arizona during April, May, or September, make sure you have an allergy treatment plan that works for you before your trip. During your trip, check the local pollen count daily to adjust your plans accordingly.

When Does Allergy Season End?

In Arizona, winter typically is mild. This means that depending on what you’re allergic to, you might not get a break from your seasonal allergies at all. In particular, Juniper trees produce pollen in the winter and cause issues for many residents.

If you suffer from indoor allergies, such as allergies to dust, pet dander, or mold, you might also notice that they worsen during the winter if you spend more time inside than usual.

Allergy Symptom Relief and Treatment

Allergies can feel difficult to manage, but there are several different methods you can try out to decrease or eliminate your allergy symptoms.

Limit Exposure

An effective method of decreasing your symptoms is limiting your exposure to the allergens that are triggering your allergies. While pollen can be difficult to avoid, there are ways that you can decrease your exposure to pollen in Arizona.

  • Check daily pollen count: Keep an eye on pollen levels to see how high they are in Arizona for the day. If it’s a high pollen count, try limiting your time outside that day. Pollen tends to be at its highest in the morning and afternoon in Arizona. Evening hours will be the best time to go outside during the Arizona allergy season.
  • Wear a mask outdoors: Wearing a dust mask when you go outside in Arizona can help prevent pollen from getting in your airways. Since Arizona has a dry climate with frequent breezes, it makes it easy for pollen to travel.
  • Clean regularly: Pollen is a very sticky substance, meaning it’ll get in your home and on you and your clothes. Be sure to clean your house and do laundry frequently. Also, make sure to shower after being outdoors to wash off any pollen. If you have pets, make sure to wash pollen off of them after they’ve been outdoors.
  • Keep windows closed: Opening your windows will allow for more pollen to get into your home. If you can, keep your windows closed and run your A/C instead for the duration of the allergy season in Arizona.
  • Install a HEPA filter: Installing a HEPA filter on your A/C can help reduce the pollen levels circulating in your home.


Over-the-counter (OTC) medications are widely available in Arizona, and they provide short-term relief from your allergy symptoms. If you find that antihistamines, nasal sprays, and eye drops don’t provide enough relief from your seasonal allergies, you can look into allergy treatments that will provide long-term relief instead of just masking your symptoms.

Sublingual Immunotherapy

If you want lifelong relief from your seasonal allergies in Arizona, sublingual immunotherapy is the best solution. Sublingual immunotherapy involves exposing your immune system to small doses of the allergens that trigger your allergies. Through this exposure, your body becomes desensitized to your allergies, providing long-term relief. Sublingual immunotherapy is just as effective as allergy shots, but it can also be taken from the comfort of your home.

Getting sublingual immunotherapy in Arizona is easy and convenient. You can get it shipped right to your home!
