What Are Seasonal Allergies?

Seasonal allergies only occur at specific times of the year because the term typically refers to allergies that are triggered by pollen. Plants only release pollen during certain times of the year, meaning these allergies usually aren't year-round. Phoenix's primary producers of pollen are grasses, trees, and weeds.

When Is Phoenix, AZ Pollen Season?

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

In Phoenix, grass pollen is mainly produced during the summer months. Weeds primarily produce pollen in the fall, but these plants can produce pollen well into the winter months. Phoenix residents can encounter tree pollen year-round, especially in both the winter and spring.

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

When Does Allergy Season Start?

Because Phoenix has a mild winter, seasonal allergies will take place year-round. This is a more extended allergy season when compared to most other places. Because Phoenix’s allergy season never stops, it can be a frustrating experience for allergy sufferers.

What Months Are Phoenix Allergy Season?

In Phoenix, 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 are lower in Phoenix.

If you have seasonal allergies and are traveling to Phoenix 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 Phoenix, winter typically is mild. This means that depending on what you’re allergic to, you might not get a break from your seasonal allergies. 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

Dealing with your allergies can feel overwhelming. However, there are some steps you can take to manage or eliminate your symptoms.

Limit Exposure

Avoiding pollen altogether is impossible, but there are ways to decrease your exposure in Phoenix. Limiting pollen exposure is an effective way to lessen your symptoms.

  • Check daily pollen count: Keep an eye on pollen levels and try to stay indoors on high pollen count days. Pollen tends to be at its highest in the morning and afternoon in Phoenix, making the evening the best time to go outside during the Phoenix allergy season.
  • Wear a mask outdoors: Wearing a dust mask when you go outside in Phoenix can help prevent pollen from getting into your airways. Since Phoenix 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 Phoenix.
  • 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 Phoenix and provide short-term relief from allergy symptoms. While antihistamines, nasal sprays, and eye drops can mask symptoms, they may not provide enough relief from your seasonal allergies. There are allergy treatments that will provide long-term relief instead of just masking your symptoms.

Sublingual Immunotherapy

Sublingual immunotherapy is the best solution if you want lifelong relief from your seasonal allergies in Phoenix. 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 Phoenix is easy and convenient. You can get it shipped right to your home.
