Boise Ranked One of the Worst Cities for Allergies
If you live in Boise and struggle with seasonal allergies, you’re not alone. According to the latest report from the Asthma and Allergy Foundation of America, Boise ranked #1 on the 2026 “Allergy Capitals” list, making it one of the most challenging places in the United States for people with pollen allergies.
For many residents across the Treasure Valley—including Boise, Meridian, Nampa, Eagle, and Caldwell—this ranking confirms what they already experience each spring and summer: long allergy seasons and high pollen levels.
What surprised many people, however, is how quickly Boise climbed the rankings.
In 2025, Boise ranked 95th, meaning allergy conditions were considered relatively mild compared to other U.S. cities. But in just one year, the city jumped dramatically to the top of the list.
So what changed?
Why Allergies Are Getting Worse in Boise
The AAFA ranks cities based on several factors, including:
- Pollen counts
- Use of over-the-counter allergy medications
- Access to board-certified allergists
Boise’s jump in the rankings appears to be largely driven by higher pollen levels and longer pollen seasons.
In recent years:
- Tree pollen has been appearing earlier in the year
- Pollen seasons are lasting longer
- Grass pollen levels have increased
- More days are classified as “high” or “very high” pollen
Environmental factors may also be contributing. Warmer temperatures and changing weather patterns can create ideal conditions for plants to produce more pollen and extend allergy seasons.
For people living in the Treasure Valley, this can mean weeks—or even months—of sneezing, congestion, itchy eyes, and sinus pressure.
Seasonal Allergies Affect More Than Just Your Nose
Seasonal pollen allergies can impact far more than your sinuses.
Many patients experience symptoms that affect their daily quality of life, including:
- Persistent nasal congestion
- Sneezing and runny nose
- Itchy or watery eyes
- Sinus pressure or headaches
- Fatigue from poor sleep
Pollen exposure can also trigger related allergic conditions such as:
- Allergic rhinitis (hay fever)
- Allergic asthma
- Allergic conjunctivitis
For people with asthma, pollen allergies can even worsen breathing symptoms.
If your symptoms return every year or seem to be getting worse, it may be a sign that allergy testing or treatment could help.
You Don’t Have to Suffer Through Allergy Season
Living in a high-pollen area like Boise doesn’t mean you have to simply tolerate allergy symptoms.
Today, allergy care offers many effective treatment options that can significantly reduce symptoms and improve quality of life.
Depending on your needs, treatment may include:
- Allergy testing to identify triggers
- Personalized treatment plans
- Prescription allergy medications
- Allergy immunotherapy (allergy shots or drops)
- Strategies to reduce pollen exposure
Immunotherapy treatments can even help train the immune system to become less sensitive to allergens over time.
