Worst U.S. Cities for Spring Allergies in 2026 Revealed

As the spring season approaches, many allergy sufferers may find themselves bracing for worsening symptoms. The Asthma and Allergy Foundation of America (AAFA) has released its latest ranking of U.S. cities where residents are most affected by seasonal allergies, highlighting a growing concern linked to climate change.

According to the AAFA’s findings, pollen seasons are becoming longer and more intense, leading to increased allergy symptoms for many individuals. Experts, including Noah Greenspan, a clinical specialist in cardiopulmonary physical therapy, note that environmental conditions are playing a significant role. “Allergy seasons are getting longer and worse all the time,” he explained, emphasizing that higher temperatures and humidity levels contribute to a rise in allergens, making outdoor activities more challenging for those with sensitivities.

The AAFA’s ranking of the most difficult cities for pollen allergies in 2026 includes factors such as pollen scores from trees, grasses, and weeds, the prevalence of over-the-counter allergy medications, and the availability of allergy specialists. Notably, this year, a number of cities from the western United States have made their way into the top 20, reflecting shifts in pollen distribution and environmental conditions.

The top 20 U.S. cities for spring allergies in 2026 are as follows:

1. Boise, ID
2. San Diego, CA
3. Tulsa, OK
4. Provo, UT
5. Rochester, NY
6. Wichita, KS
7. Raleigh, NC
8. Ogden, UT
9. Spokane, WA
10. Greenville, SC
11. San Francisco, CA
12. Minneapolis, MN

15. Colorado Springs, CO
16. Little Rock, AR
17. Toledo, OH
18. New Orleans, LA
19. Winston-Salem, NC

For those living in these cities or elsewhere and facing seasonal allergies, the AAFA and the American College of Allergy, Asthma, and Immunology (ACAAI) recommend several strategies to help manage symptoms.

Residents are encouraged to stay informed about local pollen counts and limit outdoor activities during peak pollen times. Keeping windows closed and utilizing air conditioning can also help filter out allergens. Regularly changing HVAC filters is crucial, especially during allergy season.

To further minimize pollen exposure, individuals should consider removing shoes at the door, changing clothes after outdoor activities, and showering before bedtime. Wearing sunglasses outside can provide additional protection for the eyes against pollen.

For those who experience persistent allergy symptoms, over-the-counter medications such as antihistamines, nasal sprays, and eye drops may offer relief. Health professionals suggest starting these treatments ahead of the typical allergy onset, ideally two weeks prior to the start of symptoms from previous years.

Regular allergy testing can also be beneficial for understanding specific triggers and managing symptoms more effectively. As the spring season arrives, staying proactive about allergy management can lead to a more comfortable experience for those affected.
