Why Do Allergies and Asthma Get Worse in September?

What You Need to Know About the “September Peak”

Every fall, millions of Americans find themselves coughing, sneezing, and wheezing, and for many, it’s not just seasonal. Doctors and researchers have long documented a dramatic spike in asthma-related emergency room visits every September, especially among children. Known as the “September Asthma Peak” or “Asthma Peak Week,” this surge is fueled by a combination of fall pollen, viral infections, indoor allergens, and back-to-school exposures.

“Allergy and asthma exacerbations are common in September due to seasonal ragweed pollen and increased exposure to respiratory illnesses in school settings,” explains Afreen Quraishi, PA-C, a certified physician assistant at Schweiger Dermatology & Allergy in New Jersey.

For patients with allergies or asthma, understanding and preparing for this time of year is crucial.

What causes the “September Peak”?

Several overlapping factors contribute to the sharp increase in allergy and asthma symptoms at the start of the school year:

  • High ragweed pollen levels: Ragweed season begins in late August and peaks in mid-to-late September in the northeast.
  • Viral infections: Back-to-school means close contact and increased exposure to respiratory viruses like rhinovirus, a common asthma trigger.
  • Indoor allergens: With cooler mornings, students and adults spend more time indoors where dust mites and mold may be lurking.
  • Lapse in medication use: Some patients stop using their controller inhalers or allergy meds over the summer, leaving them more vulnerable in the fall.

“This time of year is strongly correlated with asthma exacerbations, particularly in children,” adds Afreen. “It’s a perfect storm of pollen and viruses.”

Don’t Wait for Symptoms: Be Proactive

Many patients don’t realize just how predictable this seasonal spike is—and how preventable it can be with a little planning. Instead of waiting for symptoms to worsen, allergy and asthma sufferers can get ahead of the season.

“I wish more patients would stock up on oral antihistamines and nasal steroids in advance,” says Afreen. “Treating allergy symptoms early—like itchy eyes or congestion—can prevent more serious complications like sinus infections.”

How Allergy Testing Can Help You Avoid the ER

If your allergies or asthma worsen every fall, it may be time to stop guessing and start testing. Identifying your specific triggers through allergy testing allows providers to create a personalized treatment plan, which may include immunotherapy—a long-term solution that helps retrain your immune system.

“Allergy testing and immunotherapy can reduce symptoms, lower your need for medications and antibiotics, and prevent potential hospitalizations,” says Afreen.

Testing is quick, safe, and available with same-week appointments at Schweiger Dermatology & Allergy.

How to Prepare for Fall Allergy & Asthma Season

Here are practical steps patients can take now to reduce the risk of severe allergy or asthma symptoms in September:

  • Start Medications Early: Begin daily antihistamines and nasal sprays before symptoms start.
  • Avoid Peak Pollen Hours: Stay indoors in the early morning and on windy days when pollen counts are highest.
  • Shower After Outdoor Activity: Remove pollen from your hair, skin, and clothes before it irritates you indoors.
  • Check School Action Plans: For children with asthma, review their asthma action plan with their doctor and school nurse.
  • Book Allergy Testing: Know what you’re allergic to so you can manage or even eliminate symptoms long-term.
