Top Allergens in Connecticut
The most common allergens affecting residents of Connecticut, ranked by severity and seasonal impact.
Oak (Quercus alba, Q. rubra, Q. velutina) Pollen
SevereOaks dominate Connecticut's mixed hardwood forests and urban canopy. Their highly allergenic wind-borne pollen is the top driver of spring symptoms in Hartford, New Haven, and New London.
Most prevalent tree allergen statewide
Birch (Betula) Pollen
SevereWhite, yellow, and gray birches are widespread across Connecticut's Northeastern Mixed Forest. Birch produces highly cross-reactive pollen linked to oral allergy syndrome, peaking late April through May.
Major Northeast allergen with high cross-reactivity
Maple (Acer rubrum, A. saccharum) Pollen
ModerateRed and sugar maple are early-pollinating dominants of New England forests, kicking off Connecticut's tree-pollen season as early as late February in mild winters.
Timothy Grass (Phleum pratense) Pollen
SevereTimothy, orchard, and fescue grasses dominate Connecticut pastures, lawns, and roadsides. The cool, humid summers extend grass-pollen exposure from late May through July.
Top grass allergen in the state
Short Ragweed (Ambrosia artemisiifolia)

Why Allergies Are Worse in Connecticut
Connecticut's humid continental climate, Long Island Sound moisture, and dense hardwood forests create overlapping tree, grass, and weed pollen seasons from March through October.
Long Island Sound Marine Moisture
Persistent coastal humidity along Fairfield and New Haven counties fuels heavy outdoor mold spore loads from late summer through October, worsening allergic asthma in shoreline communities.
Connecticut River Valley Ragweed Corridor
The fertile, low-lying river valley running from Hartford to Long Island Sound is a prime ragweed habitat, producing intense Aug–Oct weed pollen peaks.
Central Hardwood Oak-Hickory Forests
Connecticut's dominant oak, hickory, maple, ash, and birch canopy releases highly allergenic tree pollen from late March through May, with oak alone causing some of the most severe symptoms statewide.
