These Are the Worst U.S. Cities for Spring Allergies in 2026, Ranked

Why Spring Allergies Are Getting Worse Across the U.S.

If you live in one of the cities on the AAFA’s 2026 list, you might already feel the effects. But why are these places so hard on allergy sufferers? Experts point to a mix of geography, weather patterns, and climate change.

Warmer temperatures cause plants to produce pollen earlier in the year and keep producing it longer. This means your “allergy season” can stretch from late winter all the way into fall. For people living in cities like Boise, San Diego, or Tulsa, that means months of sneezing, itchy eyes, and congestion.

“We are seeing shifts in what plants grow where, and how much pollen they release,” said Dr. Nicolle Overstreet. “This directly affects how severe your symptoms are.”

In the past, the worst allergy cities were mostly in the South and Midwest. But now, Western cities like Boise, Spokane, and Provo are climbing the rankings. This is because warmer, drier winters in the West allow trees and grasses to start pollinating earlier and keep pollinating longer.

How This Affects Your Daily Life

Spring allergies are not just annoying. They can affect your sleep, your work, and your overall quality of life. When your nose is stuffy and your eyes are watery, it is harder to focus. You may feel tired all the time. Some people even develop sinus infections or asthma attacks because of untreated allergies.

“Allergies can make you feel run down and miserable,” said Noah Greenspan. “For people with asthma or other lung conditions, it can be dangerous.”

The AAFA report also notes that access to allergy specialists matters. In some cities, it is harder to find a doctor who can help you manage your symptoms. That is part of why those cities rank higher on the “worst” list.

What Experts Say About Managing Symptoms

Both Greenspan and Overstreet agree: do not wait until you are miserable to take action. The key is to be proactive.

“Start your medications before your symptoms hit,” Overstreet said. “If you know your allergies usually start in March, begin taking antihistamines in late February.”

Experts also recommend tracking your symptoms over time. This helps you see patterns. For example, you might notice that your symptoms are worse on windy days or after a rainstorm. Knowing this can help you plan your outdoor time better.

“Keep a simple log of when your symptoms flare up,” Greenspan said. “That information is very helpful when you talk to your doctor.”

Why Pollen Counts Matter

Pollen counts measure how much pollen is in the air on a given day. You can check your local pollen count online or through a weather app. When the count is high, experts say you should limit your time outside, especially in the morning when pollen levels are often highest.

“If you have to go outside, wear a mask on high-pollen days,” Overstreet suggested. “It really does help filter out some of the pollen.”

Practical Takeaways for Readers

Here is a simple plan to help you survive spring allergies in 2026:

• Check pollen counts daily. Plan outdoor activities for days when the count is low.
• Keep windows closed. Use air conditioning in your home and car instead of opening windows.
• Change HVAC filters often. Do this at least every three months, or more often during allergy season.
• Shower and change clothes after being outside. Pollen sticks to your hair, skin, and clothing.
• Remove shoes at the door. This keeps pollen from spreading through your house.
• Wear sunglasses and a hat outdoors. This helps keep pollen away from your eyes and face.
• Start allergy medications early. Antihistamines, nasal sprays, and eye drops work best when you take them before symptoms start.
• Talk to a doctor if over-the-counter meds don’t work. You may need prescription treatments or allergy shots.

Understanding the Rankings

The AAFA ranks cities based on three main factors: pollen scores, use of allergy medications, and availability of allergy specialists. A city with high pollen counts and few allergy doctors will rank higher (worse) than a city with lower pollen and more doctors.

This year, the top 20 includes several cities that were not on the list before. For example, Boise, Idaho, took the number one spot. That is a big change from past years when cities like Louisville, Kentucky, or Memphis, Tennessee, often topped the list.

“More Western cities are appearing because of changing climate patterns,” Greenspan explained. “Warmer winters and earlier springs mean more pollen for longer periods.”

What About Children and Older Adults?

Spring allergies can hit children and older adults especially hard. Kids spend a lot of time playing outside, and their immune systems are still developing. Older adults may have other health conditions that make allergies worse, like asthma or heart disease.

If you have a child with allergies, talk to their pediatrician about safe medications. For older family members, check that their allergy treatments do not interfere with other medicines they take.

“Every age group needs a different approach,” Overstreet said. “Don’t just give your child the same medicine you take. Ask a doctor first.”

Final Thoughts on Living With Spring Allergies

Spring allergies are not going away. In fact, experts say they will likely keep getting worse as the climate continues to change. But that does not mean you have to suffer all season long.

By knowing your triggers, checking pollen counts, and starting treatment early, you can reduce your symptoms and enjoy the warmer weather. The key is to be prepared and to work with a healthcare professional when needed.

“You don’t have to just put up with allergies,” Greenspan said. “There are many things you can do to feel better. The first step is understanding what you are dealing with.”
