How do pollen allergy seasons vary in the United States?

How do pollen allergy seasons vary in different regions of the United States?

Pollen allergies are a common problem in the United States, affecting millions of people every year. Pollen allergies occur when the immune system overreacts to pollen particles, causing symptoms such as sneezing, runny nose, itchy eyes, and congestion. The severity and duration of pollen allergy seasons vary depending on the region of the United States.


In the Northeast, pollen allergy season typically starts in March and lasts through May. The primary allergen during this time is tree pollen, particularly from maple, birch, and oak trees. Grass pollen becomes a problem in late May and lasts through July. Ragweed pollen, a major allergen, peaks in late August and September.


In the Midwest, pollen allergy season is similar to the Northeast, with tree pollen being the primary allergen in early spring, followed by grass pollen in late spring and summer. Ragweed pollen season begins in August and lasts through October. The pollen counts tend to be highest in the late afternoon and early evening, which is important to know for those who are particularly sensitive.


In the South, pollen allergy season starts earlier than in the Northeast and Midwest, with tree pollen appearing in late January or early February. Oak trees are particularly problematic in the South, and their pollen counts can be incredibly high. Grass pollen begins to show up in late March and lasts through the summer. Ragweed season in the South lasts from August through November. Check allergy conditions with the weather channel.

In the West, pollen allergy season varies depending on the location. In coastal areas, tree pollen season can start in January and last through June, with grass pollen becoming a problem in late spring and summer. In the mountains, however, pollen season tends to be shorter, with tree pollen peaking in late spring and grass pollen peaking in late summer. In the desert regions of the West, pollen counts tend to be low, but allergens such as sagebrush and tumbleweed can cause problems for those with allergies.

How do you manage pollen allergies?

If you suffer from pollen allergies, you know how uncomfortable and frustrating it can be to manage these symptoms. However, there are several ways to manage pollen allergies and minimize the impact they have on your daily life.

Monitor the Pollen Count

Knowing the pollen count in your area can help you plan your day and avoid outdoor activities when the count is high. You can check the pollen count in your area on various weather websites and apps.

Wear Protective Clothing

Wearing protective clothing, such as a hat and sunglasses, can help keep pollen out of your eyes and hair. You may also consider wearing a face mask to prevent inhalation of pollen.

Keep Windows Closed

Keeping windows and doors closed can help prevent pollen from entering your home. You can also use air conditioning or a HEPA air filter to help reduce pollen indoors.

Wash Your Clothes and Bedding Regularly

Washing your clothes and bedding regularly can help remove pollen that has accumulated on them. It’s also recommended to take a shower and wash your hair after spending time outdoors to remove any pollen that may be on your skin and hair.

Avoid Outdoor Activities During Peak Pollen Times

Pollen counts tend to be highest in the early morning and evening, so try to avoid outdoor activities during these times. If you do need to be outside during peak pollen times, consider wearing protective clothing and taking medication beforehand.

Use Medications for pollen allergies

There are several over-the-counter and prescription medications available to manage pollen allergies, such as antihistamines, decongestants, and nasal corticosteroids. Talk to your doctor or pharmacist to determine which medication is best for you.

Consider Immunotherapy

Immunotherapy, also known as allergy shots, can help reduce the severity of pollen allergies over time. This treatment involves receiving regular injections of a small amount of allergen, gradually increasing the dosage over time.

Use Air Purification Products for Pollen Allergies

Air purifiers equipped with filters are immensely helpful for pollen allergies. MERV 13 filters, like those found in the Field Controls Trio Induct units, or H13 HEPA filters, like those found in the Field Controls Trio Plus Portable Air Purifier, trap particles as small as 0.3 microns. Most pollen particles are around 25 microns in size, so these types of filters stop pollen from flowing throughout your home efficiently and effectively.

In conclusion, pollen allergies can be uncomfortable and frustrating, but there are several ways to manage the symptoms and minimize their impact on your daily life. By monitoring the pollen count, wearing protective clothing, keeping windows closed, washing your clothes and bedding regularly, avoiding outdoor activities during peak pollen times, using medications, considering immunotherapy, or using air purifiers, you can manage your pollen allergies and enjoy the outdoors with minimal discomfort.
