Many people associate allergies with spring — blooming trees, freshly cut grass, and pollen so thick you can see it drifting through the air. It’s practically a Texas rite of passage.

So when allergy symptoms show up in the middle of summer, flare again in the fall, or seem to quietly persist all winter long, it’s easy to wonder what’s going on. Did you catch another cold? Is it a sinus infection — again? Or is something else at play?

The truth is, allergies don’t follow the calendar. In Central Texas, different allergens become active at different times of year, which means your immune system may be reacting to one trigger after another without much of a break in between. For patients dealing with perennial allergies or year-round allergies, there may never really be an “off season” at all.

If you’ve recently moved to the Killeen or Temple area and noticed your seasonal allergies seem worse than they used to be, you’re not imagining it. Central Texas has a uniquely demanding allergy environment — and it doesn’t always match what you experienced at your last duty station or in another part of the country.

Allergies Don’t End When Spring Does

Spring is one of the busiest times of year for allergens, but it’s far from the only one.

Many allergy sufferers are sensitive to more than one trigger. As one allergen fades, another takes its place, creating a revolving door of allergic symptoms that can stretch across months. Tree pollen gives way to grass pollen. Grass pollen gives way to ragweed. And just when outdoor allergens settle down for the year, indoor allergens step up to fill the gap.

Common allergy triggers that show up across multiple seasons include tree pollen, grass pollen, weed pollen, mold spores, dust mites, and pet dander. Depending on your specific sensitivities, you may find yourself reacting during spring, summer, fall, and winter — sometimes all four.

That’s not bad luck. That’s just what year-round allergies look like.

Summer: The Seasonal Allergies That Catch People Off Guard

After spring pollen levels begin to drop, most people expect to finally catch a break. Instead, they find themselves still sneezing, still congested, still reaching for tissues — and wondering why nothing has improved.

The culprit is often grass pollen, which becomes one of the most significant outdoor allergens during late spring and summer throughout Texas. For many patients, grass pollen triggers just as strong an allergic reaction as tree pollen does — sometimes stronger. If your allergy symptoms seem to peak right around the time everyone’s firing up the lawn mower, that’s probably not a coincidence.

Summer also brings another challenge: mold. Warm temperatures and increased humidity create ideal conditions for mold spores to thrive, both outdoors in soil and vegetation and indoors around air conditioners, bathrooms, and other damp areas of the home. For patients managing allergy asthma, mold exposure can push breathing symptoms from manageable to miserable in a hurry.

A few practical steps — running air conditioners with clean filters, using air filters rated for allergen removal, and keeping indoor humidity in check — can make a real difference during summer months. But for patients with significant sensitivities, those measures may not be enough on their own.

Fall: Just When You Thought It Was Over

Summer winds down, temperatures start to drop, and you think: finally. Then the sneezing starts again.

Welcome to ragweed season.

Ragweed allergies are one of the most common causes of fall allergic rhinitis across Texas, and they have a way of surprising even experienced allergy sufferers. One reason is that ragweed pollen is a long-distance traveler — it can drift hundreds of miles through the air, which means you don’t need ragweed growing in your backyard to feel its effects.

Symptoms of ragweed allergies look a lot like the symptoms of a cold: sneezing, runny nose, nasal congestion, sinus pressure, watery eyes, and an itchy throat. That overlap is one reason fall allergies are so frequently dismissed or misdiagnosed. If your family seems to cycle through “back-to-school colds” every September, it may be worth asking whether allergies are actually the cause.

Hay fever — the informal name for seasonal allergic rhinitis — tends to peak in the fall for many Central Texas patients, and it doesn’t always respond well to the same over the counter antihistamines that worked in the spring. That’s a sign that your triggers may have shifted, and your treatment plan may need to shift with them.

Winter: Indoor Allergens Mean Indoors Isn’t Always a Safe Haven

Cold weather drives everyone inside — including the allergens.

Dust mites, pet dander, animal dander, indoor mold, and household dust don’t take a winter break. If anything, they become harder to avoid once homes are sealed up against the cold. Without fresh air circulating through the house, indoor allergen levels can build steadily throughout the winter months, triggering an allergic reaction just as reliably as any outdoor pollen.

For patients with pet allergies, the holidays can be a particular challenge. More time indoors with pets — or visits to homes with pets — means more exposure. And for anyone sensitive to dust mites, the simple act of pulling out winter bedding, blankets, and stuffed animals that have been in storage can kick off a new round of nasal symptoms.

Air filters designed to capture specific allergens can help, and washing bedding regularly in hot water reduces dust mite populations. But for patients dealing with multiple indoor allergens, environmental controls alone may not provide the relief they’re looking for.

Is It Allergies — Or Something Else?

Because allergic symptoms can show up in every season, they’re easy to confuse with other things: frequent colds, chronic sinus infections linked to year-round allergies, weather-related congestion, or just “how you feel” during certain times of year.

A few clues that allergies may be involved:

Your symptoms last longer than a typical cold (usually 7–10 days) and keep coming back. Your nasal symptoms improve when you leave a certain environment — like your house or office — and return when you go back. You notice patterns tied to specific seasons, locations, or exposures (cutting the grass, visiting a friend with cats, spending time outdoors). Over the counter medications help temporarily but never fully solve the problem.

Allergic rhinitis, hay fever, and perennial allergies can all produce symptoms that feel like a never-ending cold, including sneezing, congestion, and itchy eyes. Some patients also develop nasal polyps — small, noncancerous growths in the nasal passages — as a result of long-term inflammation from untreated allergies. Others experience asthma flares, skin reactions such as eczema with dry, itchy patches of skin, or throat irritation that can be traced back to allergen exposure without ever realizing the connection.

Food allergies add another layer of complexity. While food allergies typically cause more immediate and distinct symptoms, some patients are surprised to learn that certain foods can cross-react with environmental allergens, making seasonal symptoms worse during high-pollen periods.

The bottom line: if symptoms are persistent, recurring, or interfering with your daily life, it’s worth getting a real answer rather than continuing to guess.

Why Identifying Your Triggers Is the Most Important Step

Not all allergies are treated the same way — and not all patients respond to the same treatments.

Someone whose immune system is primarily reacting to tree pollen needs a different management strategy than someone dealing with dust mites, animal dander, or mold spores. And someone managing allergy asthma alongside allergic rhinitis needs a coordinated approach that addresses both.

Allergy testing — including skin testing and blood tests — takes the guesswork out of the equation. It identifies which specific allergens are driving your symptoms, when exposure is most likely, and which treatment options are the best match for your situation.

For patients whose symptoms aren’t well controlled by medications alone, allergen immunotherapy offers a longer-term solution. Allergy shots work by gradually exposing the immune system to small amounts of specific allergens, reducing sensitivity over time. Sublingual immunotherapy — drops or tablets placed under the tongue — is another option that some patients find more convenient, particularly for families with busy or unpredictable schedules.

Neither approach is a quick fix, but for patients who are tired of managing symptoms season after season, immunotherapy can be genuinely life-changing.

When Should You See an Allergist?

Consider scheduling an evaluation if any of the following sound familiar: your symptoms continue well beyond spring, over-the-counter medications aren’t providing enough relief, you’re dealing with recurring sinus pressure or frequent infections, allergy symptoms are disrupting your sleep or your ability to function during the day, or your asthma seems to flare with the seasons.

A healthcare provider who specializes in allergy and asthma can help you identify your specific allergens, develop strategies to avoid triggers where possible, and build a treatment plan that actually fits your life — not just a generic protocol pulled off a shelf.

Persistent symptoms don’t have to become your normal. They’re worth taking seriously.
