Allergy Season in New Orleans: What ENT Specialists Want You to Know

New Orleans, LA, nicknamed the “Big Easy”, is widely known for its rich culture, around-the-clock nightlife, vibrant music scene, and delicious cuisine. However, Louisiana’s warm and humid climate can create a unique environment and allergy experience, which can make it challenging for many allergy sufferers.

Common allergy issues such as frequent sneezing, postnasal drip, sinus pressure, headaches, and a runny nose with thin, clear nasal discharge can be frustrating, especially if they start impacting your day-to-day productivity, sleep quality, and overall comfort.

This article from ENT & Allergy of New Orleans can help patients understand the Louisiana allergy season, what might be triggering their symptoms, and learn practical strategies to support symptom management.

What Are Seasonal Allergies?

Seasonal allergies, also called allergic rhinitis or hay fever, are allergies that are triggered by pollen from different plants, trees, and grasses.

Plants release pollen at varying times, depending on their growing season. As the name suggests, seasonal allergies occur during certain seasons of the year, depending on what potentially triggers your symptoms.

You may experience allergy symptoms during only one season or throughout the rest of the year, depending on what you’re allergic to and what grows around you.

What are the common symptoms of seasonal allergies?

Symptoms of seasonal allergies vary depending on the severity of the allergies, what triggered the symptoms, and the manner of contact. Common symptoms you should be on the lookout for include:

• Frequent and uncontrollable sneezing
• Nasal congestion, causing breathing difficulties through the nose
• Runny nose with thin, clear, and watery nasal discharge
• Postnasal drip, or mucus dripping down the back of the throat
• Itchy, watery, and red eyes
• Coughing or irritated throat
• Itchy nose, throat, or roof of the mouth
• Daytime fatigue, due to poor quality or lack of sleep

Allergy Season in New Orleans, LA: What You Need to Know

Despite experiencing all four seasons, New Orleans and the rest of the state of Louisiana have a mild winter season, so the region’s mild winters and long growing season can contribute to allergen exposure across much of the year. Moreover, the state’s plethora of plant life can make it extra challenging for sensitive individuals.

According to the 2026 Allergy Capitals® report from the Asthma and Allergy Foundation of America (AAFA), New Orleans, LA, ranked 18th as the most challenging place to live with pollen allergy.

Let’s take a look at Louisiana’s allergy season throughout the year:

• Spring (February to April)

Spring season in New Orleans and the rest of Louisiana is tree allergy season, with the main culprits being oak, cedar, elm, willow, ash, pecan, maple, and mulberry. Some places may also begin experiencing high pollen levels not just from trees, but also from some grasses and weeds, making spring season notorious for high pollen levels, and may be the worst allergy season for many Louisiana residents.

• Summer (May to July)

During the summer season, grass pollen levels may be high, with ryegrass, Bermuda grass, bent grass, timothy grass, and orchard grass potentially contributing to allergy symptoms in sensitive individuals. Moreover, warmer, humid conditions may support higher levels of mold spores and dust mites, which can also trigger symptoms in sensitive individuals.

• Fall (August to November)

The fall season in New Orleans, much like the rest of the state, is weed allergy season. The main allergy triggers during this time of year include ragweed, sagebrush, pigweed, Russian thistle, and marsh elder.

• Winter (December to January)

Despite the mild winters, New Orleans residents may find some relief from common environmental irritants, although usually short-lived. However, residents need to be wary of common indoor allergens such as dust mites, mold spores, and pet dander, as people spend more time indoors.

Tips and Strategies for Managing Your Allergies in New Orleans

✔️ Limit and minimize your exposure to allergens and triggers

While you can’t fully avoid all environmental allergens and triggers, you can limit and minimize your exposure to them. It seems simple, but it is one of the most effective strategies for managing your allergies, especially during peak allergy seasons.

• Track and monitor daily pollen counts and allergen forecasts, and plan your day around them. If pollen counts are high, consider limiting your time outdoors.
• Keep your doors and windows closed, especially during high-pollen and windy days.
• Keep your home clean and take steps to reduce indoor allergen exposure. If you’re mowing the lawn, trimming trees, or removing weeds around your property, make sure you’re using proper protective gear.
• Limit your time outdoors when pollen counts are high. Check daily pollen forecasts to help plan the best times to schedule an outdoor activity.
• If you’re heading out, consider wearing a well-fitting mask to help reduce exposure to airborne pollen and other particles.
• After getting home from spending time outdoors, immediately change out of your outdoor clothes and get in the shower to wash away any pollen or particles you might have picked up. This prevents the spread of irritants inside your home.
• Use a high-quality HEPA filter in your home’s HVAC system to filter out pollen and allergens.

✔️ Over-the-counter medications for symptom support

Some over-the-counter medications may offer additional support in allergy symptom management. These medications may include:

• Antihistamines
• Decongestants
• Saline nasal sprays
• Pain relievers
• Eye drops

✔️ Ask your allergist about allergy drops

If your allergy symptoms don’t get better with other forms of treatment, your allergist may start discussing the possibility of allergy drops or sublingual immunotherapy.

Allergy drops are administered under the tongue, offering a needle-free treatment option that some patients may prefer.

Some physicians may prescribe custom-compounded sublingual allergy drops off-label for appropriate patients as a form of allergen immunotherapy. These custom-compounded drops are not FDA-approved, and individual responses vary. Your care provider can help determine whether this treatment option may be appropriate for you.

A note on FDA approval: In the United States, FDA-approved sublingual immunotherapy is available as tablets for certain allergens only. Custom-compounded allergy drops are not FDA-approved, but may be prescribed for off-label use under physician guidance and monitoring.
