When is Allergy Season in St. Louis, Missouri?

Depending on what you’re allergic to, your seasonal allergies may peak in the spring, in the fall, or affect you year-round. Learn about each of Missouri’s allergy seasons below.

Spring Allergy Season

St. Louis Missouri spring allergy season typically starts in March and extends into mid-July. Pollinating trees usually mark the start of spring allergy season and continue releasing pollen well into May. Common culprits of seasonal allergies in St. Louis include oak trees, cedar trees, hickory trees, walnut trees, and ash trees. A number of other less common trees are also responsible for seasonal allergies in St. Louis, including aspen, alder, ash, birch, beech, box elder, cottonwood, elm, mountain elder, mulberry, olive, poplar, pecan, and willow trees.

The St. Louis Missouri spring allergy season is extended by pollinating grass, which typically starts in May and ends in mid-July.

Fall Allergy Season

St. Louis Missouri fall allergy season starts with the bloom of ragweed in August and usually peaks in mid-September. Ragweed is prevalent in Missouri, and is the primary cause of seasonal allergies from late August through the first frost of early winter (Missouri’s ragweed season). Most individuals that experience allergy symptoms in the fall are allergic to ragweed. Other allergenic plants that trigger fall allergies include burning bush, cocklebur, lamb’s-quarters, mugwort, pigweed, russian thistle, sagebrush, and tumbleweed.

Seasonal Allergy Variation

• Mold levels can peak during specific weather patterns, sometimes imitating seasonal allergies. Mold grows quickly during rainy periods, and also during hot and humid periods.
• Pollen levels are usually highest in the morning, and are amplified by wind and warm weather.
• Mild winter temperatures can cause plants to pollinate early, making spring allergy season start earlier than March.
• A rainy spring can promote rapid plant growth and high pollen levels that persist into the fall.

Seasonal Allergy Diagnosis

Seasonal allergy symptoms tend to be relatively consistent from allergen to allergen.

Understanding exactly what you’re allergic to can make it much easier to navigate seasonal allergies in St. Louis and know what you should (and should not!) be avoiding. This is where allergy testing comes in. Dr. Cajigal can help you determine if your symptoms are caused by allergies and pinpoint what you’re allergic to so you can find relief.

Seasonal allergy diagnosis starts with a thorough medical history, and usually involves skin or blood tests to determine your specific allergic triggers. Once your specific triggers are known, Dr. Cajigal can help you determine how to reduce seasonal allergy triggers in St. Louis Missouri.
