Common Allergens in Texas

An allergen is a substance that triggers an allergic reaction, leading to symptoms such as a runny nose, itchy eyes, or nasal congestion.

Some of the most common allergens in Texas include:

• Tree Pollens: Pollens from Cedar, Juniper,  Birch, Oak, Pecan, Elm, and Ash trees.

• Grass Pollens: Pollens from Bermuda grass, Johnson grass, Meadow fescue, Rye, and Timothy grass

• Weed Pollen: Pollens from Ragweed, Goldenrod, and sagebrush

• Mold Spores

• Dust mite

When is Allergy Season in Texas?

Allergy season in Texas is largely year-round, especially with climate change, which is making some allergy seasons last longer than they normally do. (2) In addition, pollen levels are higher and more persistent throughout the year.

However, the types of allergens that are prevalent may differ by season (spring or summer) and by region (Central Texas, West Texas, South, or Coastal Texas).

When is Spring Allergy Season in Texas?

Spring Allergy season in Texas typically lasts from February to May, with peak pollen levels being hardest in March and May.

In Texas, the main allergen triggers in spring are tree pollens, especially those from Oak trees. 

Other trees that trigger spring allergy include:

• Pecan

• Elm

• Ash

• Cotton wood

Grass pollen from Bermuda, Johnson, Orchard, Bahia, and Timothy grass may also trigger allergies from late spring (May) into early summer (June). Molds and dust mites can also be prevalent during this time of year and cause problems for allergy sufferers.

When is Summer Allergy Season in Texas

Summer allergy season in Texas typically lasts from June through August and is dominated by grass pollen.

Common grasses that trigger allergies in Texas in the summer include:

• Bermuda

• Bahia

• Timothy

• Orchard

• Johnson grass

• Sweet Vernal

In late summer, some pollen from weeds, especially ragweed, pigweed, and sagebrush, which can also trigger an allergic reaction.

In addition, high summer humidity can cause mold spores to spike during this season, while the heat can also increase indoor allergens such as dust mites, pet dander, and mildew.

When is Fall Allergy Season in Texas?

In Texas, fall allergy season typically runs from mid-August through November, with peak allergy levels usually occurring in September and October.

Ragweed is the main contributor to fall allergies in Texas and many parts of the country. Other triggers include:

• Other weeds: Sagebrush, pigweed, marsh elder.

• Mold spores are especially common due to increased rainfall and high humidity in certain Texas cities.

In late fall, Texas residents may also start reacting to mountain cedar, also called Ashe juniper.

When is Winter Allergy Season in Texas?

Winter allergy season in Texas typically runs from December through February, with pollen levels usually highest in mid- to late January.

In Texas, the winter allergy season is also referred to as Mountain Cedar season. 

Mountain cedar pollen (from Ashe juniper trees) is especially high in Central Texas and the Hill Country. It can also affect North Texas, though it’s usually most intense in Central Texas.

Other triggers of winter allergy in Texas include:

• Mold spores

• Dust mites

• Pet dander

Texas Allergy Calendar by Location

Allergy sufferers may have different triggers and experiences depending on the part of Texas they reside in, as Texas has a wide range of weather. From the very dry climate of West Texas to the humid conditions in  East Texas.

North Texas (Dallas, Fort Worth, Denton)

Allergy season in North Texas is particularly challenging because multiple pollen seasons overlap. Dallas has been repeatedly listed as one of the worst U.S. cities for allergy sufferers. (1)

In Texas, mountain cedar allergies often start in the spring and extend into February, when trees take over.

Grass pollen dominates from late spring into summer, and ragweed pollen dominates from summer into fall. The Warm winters in North Texas can also make the pollen season longer.

Common allergy triggers in North Texas include:

• Trees: Cedar, Oak, Ash, Pecan, and Elm

• Grass:  Bermuda grass, Johnson grass, and Timothy grass

• Weeds: Ragweed, Pigweed, Sagebrush, Cedar elm

• Mold

In North Texas, pollen levels are often highest in the morning and can remain elevated through the afternoon on windy days. If possible, schedule outdoor activities for later in the day to help reduce pollen exposure.

Central Texas  (Austin, San Marcos, Waco)

Cedar pollen is the main trigger of allergies for people living in Central Texas, with pollen counts typically peaking from January to early February. Austin is considered one of the worst cities for allergy sufferers. (1)

Common allergy triggers in Central Texas include:

Winter: Mountain cedar/ashe Juniper, mold, dust mite,

Spring:  Oak, Ash, Elm, Pecan, mold

Summer: Bermuda, prairie grasses,  Pigweed, Sagebrush, dust mites, mold

Fall: Ragweed, mold, dust mites

South Texas  (San Antonio, Corpus Christi, Laredo)

South Texas's warm weather, mild winters, and high humidity mean allergy season may be year-round.

Allergy season in South Texas often starts earlier and may last longer than in North or Central Texas. San Antonio is considered one of the worst cities for allergy sufferers. (1)

Common allergy triggers in South Texas include:

Winter: Mountain cedar (especially inland around San Antonio), Elm,  mold, dust mites,

Spring: Oak, Ash, Elm, Pecan, Mulberry,  mold

Summer: Bermuda grass, Johnson grass, mold (especially in areas of high humidity like Corpus Christi), dust mites

Fall: Ragweed, pigweed, sagebrush, mold, dust mites

West Texas (El Paso, Midland, Lubbock)

West Texas, with its particularly dry climate, desert vegetation, and frequent winds, means seasonal allergies may be somewhat different from those in other regions of Texas.

In addition, because there are fewer plants in West Texas, allergy season can feel shorter. However, in spring, strong winds help carry pollen across the region, making it one of the worst seasons for allergies.

Common allergy triggers in West Texas include:

Winter: Mountain cedar (in some areas), Elm,  mold, dus tmite,

Spring: Ash, Elm, Mulberry, Cottonwood,  mold

Summer: Bermuda grass, Johnson grass, mold, dust mites

Fall: Ragweed, pigweed, sagebrush, Russian thistle, mold, dust mite

East Texas (Tyler, Longview, Nacogdoches)

East Texas allergy season is often considered one of the longest and most persistent in Texas because warm temperatures and high humidity keep pollen and mold active almost year-round. 

In addition, the dense pine forest and grasses contribute to persistent allergies in the region.

Common allergy triggers in East Texas include:

Winter: Mountain cedar (in some areas), Elm,  mold, dust mite,

Spring: Pine, Oak, Elm, Ash, Pecan, Mulberry, mold

Summer: Bermuda grass, Johnson grass, mold, dust mite

Fall: Ragweed, pigweed, sagebrush,  mold, dust mite

Gulf Coast / Houston Area (Houston, Galveston, Baytown)

Unlike other drier parts of Texas, the Gulf Coast tends to have higher levels of mold spores, dust mite, and pollen year-round due to its warm temperatures, high humidity, and coastal climate.  

San Houston is considered one of the worst cities for allergy sufferers. However, winter allergy symptoms on the Gulf Coast often appear milder than in Central Texas. (1)

Common allergy triggers in the Gulf Coast/Houston Area include:

Winter: Mountain cedar (in some areas), Elm,  mold, dust mite,

Spring: Oak, Pine, Elm, Ash, Pecan, birch, maple, mesquite, mulberry,  mold

Summer: Bermuda grass, Johnson grass, mold, dust mites

Fall: Ragweed, pigweed,  mold, dust mites

Tips for Surviving Texas Allergy Season

Here are some tips for surviving Texas allergies regardless of the season or location.

• If you own a garden, consider planting mostly low-pollen or allergy-friendly plants, such as hibiscus, orchids, begonias, caladiums, and ferns.

• Always shower after being outdoors to remove pollen from your hair, skin, and the clothes you wore outside.

• If possible, avoid hanging clothes outside to limit pollen sticking to them and being carried indoors. Consider using a dryer instead.

• Use air purifiers and change the filters regularly.  Also, change the filter in your AC unit regularly, and consider using a higher MERV rating (which measures an air filter's ability to capture smaller particles) to remove more pollen.

• Consider staying indoors during peak pollen times (10 am to 4 pm).

• Wear a mask and glasses when mowing your lawn or gardening.

• As much as possible, keep windows closed during your peak allergy season, or consider installing air conditioning, especially during the hot summer months.

• Try to keep the humidity in your home below 50% by using dehumidifiers or even air conditioning. If you live on the Gulf Coast, it's especially important to keep humidity in your home under control.

• Vacuum your carpets and wipe down dusty surfaces to reduce indoor allergy triggers from dust mites.

• Wipe down pets after they’ve been outside, since pollen can cling to fur.

• Consider using allergy medications for relief when needed.

Allergy Treatment in Texas

Some available treatments that may help you manage your allergies include:

1. Over-the-Counter Allergy Medications

Common over-the-counter (OTC) allergy medications, including Benadryl, Claritin, Allegra, and Zyrtec, help relieve and treat allergy symptoms such as congestion, runny nose, and sneezing.

OTC allergy medications typically take a few days to some weeks to work. You also have to take some (antihistamines) daily for them to be effective. (3) 

Allergy medicines such as nasal decongestants should not be taken for more than 3 days, or your symptoms may worsen.

2. Prescription Medications

If your allergy symptoms aren’t responding to OTC allergy medication or your symptoms affect your daily activities, your medical provider may recommend prescription medications like steroids, mast cell stabilizers, or leukotriene modifiers.

3. Allergy Shots (Subcutaneous Immunotherapy)

An allergy shot is a form of allergy immunotherapy that involves injecting a small dose of allergens just under the skin of your arm or thigh, with the dose gradually increasing over time.

These shots help your body develop a tolerance to the allergen's effects and, over time, can even eliminate your symptoms.

4. Allergy Drops (Sublingual Immunotherapy)

If keeping up with daily allergy medications isn’t working for you or you don't like injections, allergy drops might be a suitable alternative.

Allergy drops work just like allergy shots. However, instead of getting needled at a doctor’s office, you’ll simply take your customized allergy drops at home by placing a few drops under your tongue each day.

Just like allergy shots, allergy drops expose your immune system to your specific triggers, gradually desensitizing your body’s response to allergens and alleviating your allergy symptoms.
