Top Allergens in North Carolina
The most common allergens affecting residents of North Carolina, ranked by severity and seasonal impact.
Pine (Loblolly/Shortleaf)
ModerateLoblolly pine dominates NC's coastal plain and Piedmont forests, producing visible yellow pollen films that coat homes and cars for 2-4 weeks each spring. Most abundant single tree pollen by mass statewide.

Oak (White, Red, Live)
SevereThe dominant hardwood from the Outer Banks to the mountains, oak is the number one trigger for spring allergy sufferers per NC DEQ's Raleigh air sampler. Peak intensity hits mid-April across the Piedmont.

Hickory (incl. Pecan)
SevereOak-hickory forests blanket the Piedmont and mountain regions, with hickory producing highly cross-reactive pollen that extends tree season into late spring. Cross-reactive with pecan and walnut.
Persistent late-spring trigger across Piedmont and mountains
Bermuda Grass
SevereBermuda grass dominates lawns and pastures across North Carolina's coastal plain and Piedmont, with Bahia grass adding to the burden near the southeastern coast. Peak grass pollen hits June through July.
Dominant lawn and pasture grass statewide
Ragweed
SevereNorth Carolina's warm autumn extends ragweed season until first frost in late October on the Piedmont and into November on the coast. Pervasive on roadsides and disturbed land throughout the state.
Affects approximately 75% of pollen-allergic patients
Cladosporium/Alternaria Mold
ModerateNC's humid subtropical coastal plain, combined with hurricane-driven flooding, sustains elevated outdoor mold counts. Indoor mold persists year-round in coastal homes due to persistent humidity.
Severe for asthmatics; year-round indoors on coast

Why Allergies Are Worse in North Carolina
North Carolina spans three distinct climate zones from the humid Coastal Plain to the cool Blue Ridge, creating one of the longest and most varied allergy seasons in the Southeast. The Piedmont corridor around Raleigh and Charlotte consistently ranks among the nation's worst for spring pollen.
Piedmont Pollen Amplification Zone
Raleigh and Charlotte sit over one of the highest oak-pine densities in the eastern US. Warm Piedmont springs trigger simultaneous oak, pine, hickory, and birch release, and NC recorded its highest grass-pollen count since 1999 in March 2025.
Coastal Plain Loblolly Pine and Mold Reservoir
Eastern NC's loblolly pine plantations release enormous yellow pollen clouds while saturated Coastal Plain soils and blackwater swamps sustain year-round mold spore loads.
Hurricane-Driven Mold Spikes
Tropical systems like Florence and Helene saturate housing stock and vegetation, producing sharp post-storm Aspergillus, Penicillium, and Stachybotrys spikes that persist for months.
Blue Ridge Cooler-Climate Tree Mix
The western mountains shift the allergen profile toward birch, hemlock, eastern red cedar, and later-blooming oak, with reduced humidity but concentrated pollen in mountain coves.
Regional Differences
Coastal Plain
Hot, very humid with the longest pollen season in the state. Severe post-hurricane mold and heavy pine pollen define the coastal allergy profile.
Piedmont
Charlotte and Raleigh repeatedly rank among AAFA's top Allergy Capitals. Extreme spring oak/pine overlap with high grass and fall ragweed.
Blue Ridge / Appalachian Mountains
Cooler, drier, shorter pollen season with a distinct cool-temperate species mix. Lower mold burden but pollen trapped in mountain valleys.
