Local allergy info and sinus care for Saint Louis residents
Saint Louis experiences a humid continental climate, characterized by hot summers, cold winters, and high humidity throughout much of the year. This climate contributes to a rich variety of plant life, which in turn results in diverse and often intense allergy seasons. Residents frequently face nasal congestion and sinus discomfort due to airborne allergens that thrive in the region's changing seasons.
The abundant vegetation and moisture in Saint Louis create ideal conditions for pollen production and mold growth. As a result, many locals experience persistent allergy symptoms from early spring through fall, with sinus inflammation becoming a common complaint during peak pollen times.
Allergy season in Saint Louis generally begins in early March and extends through October. Tree pollen is most prevalent in April and May, causing sneezing and sinus pressure for many residents. Grass pollen follows, peaking in late May and June, while ragweed pollen dominates from August through October, often triggering the most severe symptoms.
This extended allergy season means sinus sufferers in Saint Louis often require year-round management strategies, especially when outdoor activities increase pollen exposure.
