Allergy season in the United States does not arrive and leave on a fixed schedule. For millions of Americans, it feels like a year-round struggle because different allergens peak at different times, and some overlap in ways that keep symptoms going from late winter through the first frost. Altus ER Lake Jackson provides prompt evaluation and treatment for severe allergy symptoms and allergic emergencies.
Texas residents face a particularly challenging allergy calendar because of the state’s mild winters and long growing seasons, which allow allergens like cedar, oak, and ragweed to thrive for longer periods than in colder climates. Knowing the allergy triggers to avoid throughout the year can help you reduce your exposure and manage symptoms more effectively before they escalate into something serious.
What Is Allergy Season?
Allergy season refers to any period of the year when airborne allergens like pollen, mold spores, and grass reach levels high enough to trigger immune responses in sensitive individuals. According to the CDC, more than 25 percent of adults and 18 percent of children in the United States experience seasonal allergic rhinitis, making it one of the most common chronic health conditions in the country. The season varies by location, climate, and which specific allergens are most prevalent in a given region at any given time of year.
When Does Allergy Season Start?
Allergy season can begin as early as January in warmer states like Texas and typically continues in some form through November, depending on the year. The start date shifts based on temperature, rainfall, and wind patterns that influence how much pollen trees, grasses, and weeds release into the air. A warmer than usual winter accelerates the timeline significantly and can cause the tree pollen season to arrive weeks earlier than expected in many parts of the country.
What Are the Worst Months for Allergies?
Different allergens dominate different months, which is why allergy sufferers often notice their symptoms shifting and changing in character throughout the year rather than appearing and disappearing all at once.
Spring Allergy Season (February to May)
Spring is the most intense allergy season for most people because it coincides with peak pollen release from trees, including oak, cedar, birch, and maple. Pollen counts can reach levels high enough to cause severe symptoms even in people with mild allergies, the rest of the year. Our spring allergies survival guide covers the most effective strategies for keeping your symptoms under control.
Summer Allergy Season (June to August)
The summer allergy season is dominated by grass pollen from species like Bermuda, Timothy, and Kentucky bluegrass, which continue releasing pollen through much of the season. Mold spores also become a significant problem during warm and humid months, particularly after heavy rainfall encourages mold growth in soil and vegetation. People experiencing eye irritation, congestion, and sneezing that does not improve in summer may be reacting to grass pollen rather than a cold.
Fall Allergy Season (August to November)
Ragweed is the dominant fall allergen and one of the most powerful triggers in the country, with a single plant capable of producing up to one billion pollen grains in a season. Mold spores also remain elevated as leaves decay on the ground and create ideal conditions for outdoor mold growth. Fall allergies often catch people off guard because the symptoms closely resemble those of cold and flu viruses circulating at the same time.
Winter Allergies (December to January)
Winter does not bring complete relief for everyone because indoor allergens like dust mites, pet dander, and mold become more problematic as people spend more time inside with windows closed. In Texas specifically, mountain cedar pollen peaks in December and January and causes an intense reaction known locally as cedar fever that affects a significant portion of the population. Many people mistake cedar fever for a cold or flu because the symptoms can be severe despite being caused entirely by pollen exposure.
What Are Common Allergy Season Symptoms?
Allergy season symptoms can range from mildly annoying to significantly disruptive and vary depending on the individual’s sensitivity and the allergens they are reacting to. Recognizing these symptoms helps you distinguish between a manageable allergy flare and something that may require medical evaluation.
- Persistent sneezing, especially in the morning or after going outdoors
- Runny or stuffy nose with clear or slightly cloudy nasal discharge
- Itchy, watery, or red eyes that worsen with outdoor exposure
- Itchy throat, ears, or roof of the mouth
- Postnasal drip is causing a persistent mild cough or throat clearing
- Fatigue and general low energy that persists throughout allergy season
- Worsening of asthma symptoms, including wheeze, chest tightness, and shortness of breath
If seasonal allergies become severe or difficult to manage, seeking allergy care can help relieve symptoms and prevent complications.
What Causes Seasonal Allergies?
Seasonal allergies occur when the immune system mistakenly identifies harmless airborne particles like pollen or mold spores as threats and mounts an exaggerated defense response. According to MedlinePlus, this triggers the release of histamine and other chemicals that cause sneezing, itching, congestion, and watery eyes. Genetics plays a significant role, but environmental exposure and age of first contact with specific allergens also influence how allergies develop over time.
How Long Does Allergy Season Last?
For people sensitive to multiple allergens, allergy season can effectively last most of the year, with brief periods of lower symptoms between the peak seasons of different plants. Tree pollen runs from February through May, grass pollen from May through August, and ragweed and mold from August through November. In Texas and other southern states, mild winters mean some level of allergenic pollen is present in the air for nearly every month of the year.
When to Go to the ER for Allergies?
Most seasonal allergy symptoms can be managed with over-the-counter antihistamines and allergen avoidance, but some reactions require immediate emergency care. If allergy symptoms have progressed into a sinus infection, our guide on when to visit the ER for sinus infections explains when to act. For persistent eye redness or discharge, our pink eye vs allergies guide can help you determine when eye symptoms need professional evaluation.
Visit Altus Emergency Centers immediately if you experience any of the following:
- Severe difficulty breathing, wheezing, or a feeling that your airway is tightening or closing
- Throat swelling, hoarseness, or difficulty swallowing that develops suddenly after allergen exposure
- Hives spreading rapidly across large areas of the body, alongside any breathing changes
- Dizziness, lightheadedness, or a sudden drop in blood pressure after exposure to a known allergen
- Confusion, extreme weakness, or loss of consciousness during or after an allergic reaction
- Chest pain or tightness that does not resolve with rest or inhaler use during an asthma flare
- Any combination of symptoms suggesting anaphylaxis, which is a severe and life-threatening allergic reaction
If you are experiencing these symptoms and searching for an ER near me, seek emergency medical care immediately.
