Spring may get most of the attention when it comes to allergies, but many people are surprised to find their allergy symptoms continuing long after the oak trees stop shedding pollen.

If you’re still dealing with a runny nose, nasal congestion, or itchy eyes in the middle of summer, you’re not alone. Year-round allergies are extremely common for Central Texas residents — and there’s a clear reason why.

In Austin, allergy season doesn’t really end. It changes. Different allergens cycle through the calendar, creating nearly continuous exposure for allergy sufferers. Understanding what’s triggering your seasonal allergies — and knowing how to manage symptoms effectively — is the first step toward finding lasting relief.

The Myth of “One Allergy Season”

Many people associate allergies with spring. In reality, multiple allergy triggers become active at different times throughout the year, and as one allergen fades, another takes its place.

That’s especially true in Austin, where weather patterns and our mild climate allow many plants to release pollen for extended periods. Ongoing symptoms may not mean your spring allergies never cleared up. You may simply be reacting to an entirely different trigger — one that occurs year round.

What Are the Most Common Allergy Triggers in Central Texas?

Before breaking down the seasons, it helps to understand the most common allergy triggers in the Austin area. These include both outdoor allergens and indoor allergens:

• Tree pollen (cedar, oak, elm)
• Grass pollen (Bermuda, Johnson grass, and others)
• Ragweed pollen
• Mold spores
• Dust mites
• Pet dander and animal dander

Many allergy sufferers are sensitive to more than one of these specific allergens, which is why allergy symptoms can feel nearly constant throughout the year. When multiple pollen seasons overlap with indoor triggers like dust mites and pet allergies, the immune system rarely gets a true break.

Spring: Tree Pollen Allergies and the Start of Allergy Season

Austin’s allergy season typically kicks off with high pollen counts from trees. Oak, cedar elm, and ash are among the biggest culprits, triggering classic allergic rhinitis symptoms:

• Sneezing
• Runny or stuffy nose
• Itchy eyes and itchy nose
• Nasal congestion
• Postnasal drip
• Sore throat from drainage
• Sinus pressure

For many patients, spring allergies feel most intense — but they’re just the beginning of the cycle. Monitoring pollen counts during this period can help you anticipate your worst days and plan accordingly.

What Happens After Spring Allergies End?

Late Spring: Grass Pollen Takes Over

Once tree pollen begins to decline in late spring, grass pollen becomes the next major concern for allergy sufferers. Common grasses throughout Central Texas continue to release pollen well into summer, producing many of the same symptoms.

Many patients notice that just when they think allergy season is winding down, symptoms continue — because grass pollen levels are still climbing. High pollen counts from grasses can trigger symptoms just as severe as those caused by tree pollen earlier in the year.

Summer Allergies in Texas: More Common Than You Think

Summer allergies in Texas are frequently underestimated. Several significant triggers remain active during the warmer months, and for patients with perennial allergies, summer can actually bring more severe symptoms than spring.

Mold Spores Increase With Heat and Humidity

Warm temperatures combined with Central Texas humidity create ideal conditions for mold growth outdoors and indoors. Airborne mold spores are a common trigger that many allergy sufferers don’t consider. Symptoms can include:

• Nasal congestion
• Coughing
• Sinus pressure
• Watery eyes
• Asthma flare-ups

Mold allergy symptoms often worsen after rain or during periods of high humidity. Using air filters indoors and keeping air conditioners well-maintained can help reduce indoor mold exposure during summer months.

Indoor Allergens Become More Significant in Summer

As temperatures climb, most people spend more time indoors with windows closed and air conditioning running. This increased time inside raises exposure to some of the most common triggers of perennial allergies:

• Dust mites — tiny creatures that thrive in warm, humid environments and are one of the most widespread indoor allergens
• Pet dander — a year-round trigger that intensifies with less fresh-air ventilation; furry friends can be a significant source of indoor allergens even for mild allergy sufferers
• Animal dander from any household pets
• Indoor mold

For many patients, indoor allergens like dust mites and pet dander contribute to allergy symptoms year round, regardless of outdoor pollen levels.

Fall Allergies in Texas: A Second Wave

Fall allergies in Texas bring a second significant wave of symptoms — sometimes catching people off guard after a relatively comfortable midsummer.

Ragweed Pollen Arrives

Ragweed is one of the most widespread causes of fall allergies and hay fever throughout Texas. Even small amounts of ragweed pollen can travel long distances on the wind, and high pollen counts from ragweed can trigger significant allergic reactions including:

• Sneezing
• Runny or stuffy nose
• Itchy nose and itchy eyes
• Sore throat
• Watery eyes
• Postnasal drip
• Worsening asthma symptoms

Patients who felt better during midsummer may experience a sharp return of symptoms once ragweed pollen levels rise in late summer and early fall. This pattern is one reason that year-round allergies can feel relentless — pollen seasons overlap in ways that leave very little breathing room.

Winter Allergies in Austin: Mountain Cedar Season

While winter brings relief from outdoor allergens in much of the country, Central Texas is a different story entirely.

Mountain Cedar Peaks in Winter

Mountain cedar is one of Austin’s most notorious allergens, and unlike most trees, cedar season peaks during the winter months. Many allergy sufferers in Central Texas experience their most severe symptoms of the year during this period:

• Extreme nasal congestion
• Fatigue and body aches
• Sinus pressure and headaches
• Sneezing
• Itchy eyes and itchy skin
• Worsening asthma

If you feel worse in January than you do in April, mountain cedar may be the reason. This is a key distinction between allergy season in Central Texas and the rest of the country, and it’s one that surprises many patients — and their healthcare providers — who aren’t familiar with local weather patterns and pollen seasons.

Could You Be Reacting to Multiple Allergy Triggers?

Many allergy sufferers assume they have a single trigger. In reality, it’s common to have allergic reactions to several specific allergens at once — tree pollen, grass pollen, ragweed pollen, mold, dust mites, and pet dander — whose seasons and exposure windows overlap throughout the year.

When multiple triggers compound across the calendar, symptoms can feel constant. This is sometimes misread as a single persistent allergy, when in fact different allergens are responsible for symptoms at different times.

This is exactly why allergy testing is so valuable. Through skin testing or blood tests, a specialist can identify your specific allergens and help you understand exactly what your immune system is reacting to. That information allows your provider to build personalized treatment plans — rather than relying on generic symptom management.

How to Manage Year-Round Allergy Symptoms

While allergy testing and treatment are the most effective long-term strategies, there are steps allergy sufferers can take to reduce daily exposure and manage symptoms:

• Monitor pollen counts and limit outdoor activity on high pollen count days
• Use HEPA air filters indoors to reduce airborne allergens
• Keep air conditioners maintained and change filters regularly
• Try saline nasal rinses to clear allergens from nasal passages and ease nasal congestion
• Use eye drops formulated for allergic reactions to relieve itchy, watery eyes
• Wash bedding frequently to reduce dust mite exposure
• Bathe pets regularly to minimize pet dander and animal dander in the home
• Avoid triggers when possible, especially during peak pollen seasons

These strategies can help manage symptoms, but they’re most effective when combined with a proper diagnosis and treatment plan from a specialist in allergy and asthma.

Treatment Options for Seasonal and Year-Round Allergies

Once your specific allergens are identified, there are several effective treatment options available:

• Medications — antihistamines, nasal corticosteroids, and decongestants can provide seasonal allergy relief for mild to moderate symptoms
• Eye drops and nasal sprays — targeted treatments that address localized symptoms
• Allergy shots (immunotherapy) — a long-term treatment that gradually desensitizes the immune system to specific allergens; allergy shots are one of the most effective options for patients with more severe symptoms or multiple triggers
• Other treatments — your provider may also recommend sublingual immunotherapy or additional therapies depending on your needs

The right treatment varies depending on your individual allergy profile, symptom severity, and lifestyle. A specialist can help you find the right treatment approach.

When Should You See an Allergist?

Consider scheduling an evaluation if:

• Your allergy symptoms last longer than one season
• Over-the-counter medications aren’t providing enough seasonal allergy relief
• Symptoms interfere with sleep, work, or daily activities
• You experience recurring sinus infections or nasal polyps
• Asthma symptoms worsen during certain times of year
• You’re unsure what’s triggering your symptoms

The sooner your specific allergens are identified, the sooner you can begin effective allergy treatment — and stop spending every season guessing.

Take Control of Your Year-Round Allergies

If it feels like your allergies never take a season off — you’re probably right.

In Austin, allergy season shifts throughout the year. Tree pollen, grass pollen, ragweed, mold, mountain cedar, dust mites, and pet dander create a near-continuous cycle of exposure for allergy sufferers.
