Why Your Ragweed Allergy Feels Worse in September (And What You Can Do About It)

Do you dread going out every year in September because you’re afraid of the constant sneezing it could possibly bring? Well, you're not alone. 


Just when the worst of the summer heat starts to ease up, ragweed season swoops in to remind you that allergy sufferers in Texas don't get much of a break. The weather could be nice and warm, but you might already have gone through a box of tissues before lunch, and you know what it is, from experience – Ragweed pollen!


September is Texas’ allergy season. It is when ragweed pollen peaks. This blog explains why that happens, what seasonal allergy symptoms to watch for, and what you can do about September ragweed allergy symptoms. 


If the seasonal allergy symptoms are severe, schedule an appointment with Premier Allergy Texas for an evaluation as soon as possible. Our team is determined to keep you healthy this ragweed season.

Why Is September Peak Ragweed Season?

Ragweed usually begins producing pollen in mid-August. By September, ragweed plants are producing pollen on a large scale. One ragweed plant can produce up to 1 billion pollen grains

Why does ragweed pollen production rise suddenly in September?

  • Change in Temperature
    The fall in temperature at night acts as the plant’s cue that fall is coming, and it needs to reproduce faster. 

  • Wide Geographic Spread
    Ragweed grows all across Texas. So that naturally means more pollen coming a Texan’s way. 

  • Pollen Timings
    Peak pollen production hours are around 10 am to 3 pm, when most people are outside working or taking in the summer sun. 

Common Symptoms During Peak Ragweed Season

Ragweed allergy symptoms tend to mimic a cold. Sometimes it is easy to mistake seasonal allergy symptoms for a cold. 

The key giveaway that it's allergies and not a cold? Duration. A cold usually clears up in 7–10 days. Ragweed allergies can drag on for weeks, sometimes lasting well into October or even November in parts of Texas, depending on when the first hard frost arrives.

A few symptoms include:

  • Sneezing
  • Runny nose
  • Nasal congestion
  • Headaches
  • Irritated eyes
  • Itchy throat

If someone has asthma, ragweed pollen can also aggravate asthma symptoms, leading to increased coughing and wheezing.

Why Are Ragweed Allergy Symptoms Worse on Windy Days?

Ragweed pollen is lightweight and specifically built to travel by wind, sometimes hundreds of miles. On calm days, pollen tends to settle closer to the ground and is more localized. But on windy days, that pollen gets kicked up, carried across neighborhoods, and dispersed in higher concentrations through the air you're breathing.


Texas and winds go hand in hand. As cold fronts begin to push through in September, each gust of air can stir up fresh clouds of pollen. 

Ironically, a beautiful, breezy fall day, the kind that makes you want to open your windows or sit outside, can often prove to be the worst possible day for your sinuses.



Rain, on the other hand, tends to temporarily knock pollen out of the air, which is why allergies often feel better right after a good rainstorm, before pollen count rebounds in a day or two.

How to Reduce Daily Pollen Exposure

Ragweed allergy tends to be worse in the Eastern and Midwestern U.S., including Texas. You can't control the weather or make ragweed pollen disappear, but you can make some smart adjustments to reduce how much pollen you're exposed to each day:

  • Prioritize allergy testing
    Allergy testing helps you better understand your allergy triggers and allows providers to plan your treatment accordingly. Contact Premier Allergy Texas to schedule an appointment for allergy testing before the allergy season starts. 

  • Check daily pollen forecasts. 
    Many local weather apps and allergy-tracking websites provide daily pollen counts specific to Texas cities. Use this to plan outdoor activities during low-pollen periods.

  • Avoid outdoor activities during peak hours. 
    Limit outdoor exercise or yard work between 10 a.m. and 2 p.m., when ragweed pollen tends to be at its highest.

  • Keep windows closed. 
    As tempting as it is to enjoy the cooler September air, keeping windows shut (and running the AC with a good filter) keeps outdoor pollen from turning your living room into an allergy zone.

  • Shower and change clothes after being outside. 
    Pollen loves to cling to hair, skin, and clothing. A quick rinse after yard work or a walk can make a big difference.

  • Use a HEPA air purifier indoors. 
    This helps filter out pollen that sneaks in through doors, vents, or on your clothes.

  • Wash bedding regularly. 
    Pollen can settle on sheets and pillowcases, especially if you've been outside and then hopped straight into bed.

  • Wear sunglasses outdoors. 
    It sounds minor, but it helps keep pollen out of your eyes, reducing that itchy, watery feeling.

None of these will eliminate ragweed exposure completely, but together they can reduce allergy symptoms. Check out our latest post on the ten most frequent allergy triggers affecting San Antonio residents. You can also find tips to prepare for allergy season here. 

Best Treatment Options for Ragweed Allergies

There are both over-the-counter (OTC) and prescription medications for allergies. Some of them are:

  • Antihistamines
    This type of medication blocks the chemicals your body produces in response to an allergy. This can reduce allergy symptoms.

  • Nasal corticosteroids
    These nasal sprays reduce inflammation and congestion. 

  • Leukotriene inhibitors
    These medications block chemicals your body releases during an allergic reaction.

  • Decongestants
    This medication helps shrink your nasal passages and relieves congestion and a runny nose. 

  • Antihistamine/decongestant
    This combines both an antihistamine and a decongestant. 

  • Cromolyn sodium
    This nasal spray blocks chemicals that cause allergic reactions.

  • Immunotherapy
    Premier Allergy Texas strongly recommends
    allergy shots, which help your body build resistance to allergens and provide long-term relief from ragweed allergy symptoms. 

Discuss the side effects and risks of allergy medications with your healthcare provider.

Is Allergy Immunotherapy Right for You?

Immunotherapy, or allergy shots, is an almost century-old method for treating allergy symptoms. Allergy shots can lead to lasting remission of allergy symptoms and may help prevent the development of asthma and new allergies. 



For most people, allergy shots are usually safe. But allergy shots contain tiny amounts of allergens. If you have an allergic reaction to an allergy shot, your allergist will quickly give you medicine to stop it.
