How to Manage and Treat Your Allergies in Houston, Texas

Common Houston Allergies

Houston’s climate makes it a hotspot for allergens nearly year-round. From tree and grass pollen to mold and ragweed, allergens thrive in the city’s warm, humid conditions. If you’re struggling with sneezing, congestion, itchy eyes, or other allergy symptoms, one of these common Houston allergens could be the culprit:

‍

Tree Pollen

Tree pollen season in Houston typically starts in January and can last through September. Mild winters allow trees to produce pollen in Houston for longer periods, making allergies worse. The most troublesome trees for allergy sufferers include:

‍

• Cedar – A major cause of "cedar fever" in the winter and early spring.
• Oak – Produces heavy pollen in the spring, coating surfaces in yellow dust.
• Pine – High pollen counts in late winter and early spring.
• Ash – Peaks in the spring, triggering allergies with fine pollen particles.
• Pecan – Blooms in the spring and is a strong allergen for many Houstonians.
• Elm – Common in urban areas, with peak pollen season in late winter and early spring.

‍

Grass Pollen

Grass pollen is one of the most common allergy triggers worldwide, and Houston is no exception. Grasses release pollen from March through July, with symptoms often worsening during peak summer months. The most allergy-inducing grasses in Houston include:

‍

• Timothy – A highly allergenic grass that blooms in late spring and early summer.
• Orchard – Common in lawns and meadows, peaking in spring and summer.
• Sweet Vernal – Produces a strong pollen that triggers allergies in spring and early summer.
• Bahia – Grows aggressively in warm climates and releases pollen in summer.
• Bluegrass – A common lawn grass that produces allergenic pollen in spring and summer.

Ragweed Pollen

Ragweed is one of the most notorious fall allergens, typically causing allergy symptoms from mid-August through November in Houston. Just one ragweed plant can produce over a billion grains of pollen, making it nearly impossible to avoid. If you suffer from fall allergies, ragweed is likely to blame.

‍

Mold

Houston’s humidity and frequent rain make mold a year-round issue, especially indoors. Mold spores can trigger allergic reactions, worsen asthma symptoms, and lead to chronic sinus problems. Common mold sources include:

‍

• Damp areas in homes, such as bathrooms and basements
• Flood-damaged buildings and walls
• Decaying leaves and outdoor plant debris

‍

If you’re experiencing persistent allergy symptoms, it’s important to identify the triggers and seek effective treatment options. Houston’s allergy season may be long, but relief is possible with the right care and prevention strategies.

‍

How long is allergy season in Houston?

Houston’s climate creates the perfect environment for pollen to thrive nearly year-round. Allergy season typically begins in January with tree pollen, followed by grass pollen peaking from March through July and ragweed season kicking in from mid-August to November. While some relief comes in the winter months, mold and indoor allergens remain a constant issue. Unfortunately, as winters continue to warm, pollen seasons are lasting even longer, leading to more intense allergy symptoms for many Houstonians.

Seasonal Allergy Symptoms: 

Whether it’s tree pollen in the spring, grass pollen in the summer, or ragweed in the fall, allergens can make daily life miserable. Some of the most common allergy symptoms include:

‍

• Excessive sneezing – Frequent sneezing fits, especially when outdoors.
• Runny nose – Clear, watery discharge caused by airborne allergens.
• Nasal congestion – Stuffy nose that makes it hard to breathe.
• Allergy fatigue – Feeling constantly tired or sluggish due to an overactive immune response.
• Itchy, watery, or burning eyes – A classic sign of seasonal allergies.
• Coughing – Often triggered by postnasal drip or airborne irritants.
• Rashes or hives – Skin reactions caused by allergens like pollen or mold.
• Shortness of breath or wheezing – Can be especially problematic for those with asthma.

‍

Over-the-counter antihistamines like Benadryl can provide temporary relief, but they only mask the symptoms. For real, long-term relief, explore our allergy treatments that target the root cause and help you live allergy-free.

How to prevent Houston allergies 

Managing allergies in Houston starts with preparation and prevention. Taking proactive steps can help reduce symptoms and improve your quality of life during the year-round Houston allergy season. Here are some essential tips to minimize allergy flare-ups:

‍

• Get an allergy test – Knowing what you’re allergic to allows you to take targeted precautions before peak allergy season hits.
• Use a HEPA air filter – These filters trap pollen, dust, and other allergens to keep your indoor air cleaner.
• Wash off after being outside – Allergens stick to your hair, skin, and clothing, so showering and changing clothes can prevent them from spreading inside.
• Time your outdoor activities – Pollen counts are highest in the morning, so schedule outdoor chores for later in the day when possible.
• Wash bedding frequently – Clean sheets and pillowcases in hot, soapy water to remove lingering allergens.
• Close windows and doors – Keep pollen and mold spores out by sealing your home during peak allergy seasons.
• Check the daily allergy report – Stay informed about the Houston pollen and mold counts by checking local resources like Houston Health or Pollen.com.

‍

By taking these steps, you can reduce allergen exposure and better manage your symptoms.

Frequently asked questions about allergies in Houston

We answer some of the most common questions about allergies in Houston, helping you understand symptoms, treatment options, and how to find relief.

When is allergy season in Houston?

Allergy season in Houston is almost year-round due to the warm, humid climate. Tree pollen starts as early as January and can last through the spring months, followed by grass pollen in the summer. Ragweed takes over in late summer and continues into the fall, while mold is a year-round concern, especially during our rainy periods. Because allergens are present for much of the year, it’s important to stay proactive with treatment to manage symptoms effectively.

Why are my allergies so bad in Houston right now?

There could be several reasons why your allergies are particularly bad right now in Houston. The city’s warm, humid climate creates the perfect environment for allergens like tree pollen, grass pollen, and mold to thrive. Depending on the time of year, one or more of these allergens could be at their peak, making symptoms worse. Additionally, Houston's fluctuating weather patterns and rainfall can lead to higher pollen counts and mold growth. If your symptoms are persistent, it might be time to consider an allergy test to pinpoint exactly what’s affecting you and find a treatment plan that works.

Is Houston a bad city for allergies?

Yes, unfortunately, Houston is known to be a challenging place for people with allergies. With a longer growing season and high pollen counts, many residents experience symptoms from tree pollen in the spring, grass pollen in the summer, and ragweed in the fall. Combined with frequent rainfall and high humidity, Houston's environment can make allergy sufferers more susceptible to persistent symptoms. However, with proper testing and treatment, relief is possible.
