Local Allergy Overview

Lewiston, Maine, experiences a humid continental climate characterized by cold winters and warm summers. The region's diverse flora and seasonal weather patterns create a moderate to high allergy environment throughout much of the year. Residents often face challenges from airborne pollen, mold spores, and indoor allergens, especially during the spring and fall months. Understanding Lewiston’s unique climate helps locals prepare and find effective sinus relief solutions.

Top Allergens in Lewiston

Maple and Oak Tree Pollen: These native trees release pollen in early to mid-spring, triggering nasal congestion and sinus pressure for many residents.
Ragweed: Ragweed pollen is a major fall allergen in Lewiston, peaking from late August through September, often causing sneezing and sinus irritation.
Mold Spores: Due to Lewiston’s moist climate, outdoor and indoor mold spores are common allergens, especially during damp autumn months and after heavy rains.
Dust Mites: Common indoors year-round, dust mites thrive in humid conditions and can exacerbate sinus inflammation and allergy symptoms.

Allergy Seasonal Calendar

Spring (March - May): Tree pollen season dominates, with maple, oak, and birch pollen causing early allergy symptoms.

Summer (June - August): Grass pollen peaks early summer, but overall allergy intensity may decrease mid-summer with fewer airborne allergens.

Fall (September - November): Ragweed pollen is prevalent, alongside increased mold spores due to falling leaves and damp weather.

Winter (December - February): Outdoor allergens drop, but indoor allergens like dust mites and pet dander can worsen sinus issues during colder months.
