Local Allergy Overview

New Orleans' humid subtropical climate contributes to a long allergy season, with moisture promoting mold growth and pollen production. The city's abundant greenery and proximity to wetlands often exacerbate sinus irritation for allergy sufferers throughout much of the year.

Top Allergens in New Orleans

Oak Pollen: Common in New Orleans during spring, oak pollen triggers seasonal allergic reactions and sinus inflammation.
Spanish Moss Mold: The humid environment fosters mold growth on hanging Spanish moss, releasing spores that irritate nasal passages.
Ragweed: Thriving in late summer and fall, ragweed pollen is a potent allergen causing sneezing and sinus congestion.
Dust Mites: High indoor humidity levels encourage dust mite populations, which can worsen year-round sinus issues.

Allergy Seasonal Calendar

Allergy season in New Orleans runs from February through November, with varying intensity:

Spring: Spring in New Orleans brings heavy oak pollen and increasing mold spores due to frequent rains, causing early sinus allergies.
Summer: The hot and humid summer promotes indoor allergens like dust mites and mold, intensifying sinus discomfort.
Fall: Fall features a surge in ragweed pollen and lingering mold spores, extending the allergy season well into November.

Due to this extended season, consistent sinus care is essential to maintain relief and comfort.
