Local Allergy Overview

Baltimore experiences a humid subtropical climate with hot, humid summers and mild to cool winters, which can exacerbate allergies year-round. The city's proximity to both urban areas and waterways creates a unique environment where pollen and mold spores thrive, often causing sinus irritation for residents.

Top Allergens in Baltimore

Eastern Red Cedar: Common in Baltimore's parks and residential areas, this tree releases pollen in late winter and early spring, often triggering early-season allergies.
Oak Pollen: Oak trees are widespread throughout Baltimore and release large amounts of pollen in spring, making it a major contributor to seasonal sinus issues.
Grass Pollen: Various grasses prevalent in Baltimore neighborhoods and open spaces release pollen in late spring and early summer, worsening sinus symptoms.
Mold Spores: The humid conditions around Baltimore’s waterways and in shaded urban areas promote mold growth, especially in fall, aggravating sinus allergies.

Allergy Seasonal Calendar

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

Spring: Spring in Baltimore is marked by a surge in tree pollen, especially from oak and red cedar, causing increased sinus inflammation from February through May.
Summer: During the summer months, grass pollen peaks and the hot, humid weather encourages mold growth, both contributing to persistent sinus discomfort.
Fall: Fall brings a decline in pollen but a rise in mold spores due to damp leaves and increased moisture, often prolonging sinus issues into November.

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