Charlotte, NC sits in the humid subtropical Piedmont region, a climate that fosters a long, intense allergy season stretching from late winter through fall.
Tree pollen kicks things off early, with oak, pine, cedar, juniper, maple, birch, sweetgum, and hickory releasing heavy pollen loads from February through May. Pine pollen is especially visible, coating cars and surfaces in yellow dust, though oak is typically the more potent allergen.
As tree season winds down, grass pollen takes over from May through July, with Bermuda, Timothy, orchard, and fescue grasses dominating lawns and open fields across the region.
By late summer, weed pollen surges into prominence, peaking from August through October. Ragweed is the principal culprit, joined by pigweed, lamb's quarters, plantain, and sorrel. Overlap is common—lingering grass pollen often collides with early ragweed in August, intensifying symptoms for multi-sensitive sufferers.
Beyond pollen, Charlotte's warm humidity fuels year-round mold growth, both outdoors in leaf litter and indoors in damp spaces, while dust mites thrive in the muggy climate. Ozone and vehicle-related air pollution can further aggravate symptoms during hot months.
Overall, Charlotte's allergy profile is defined by a prolonged, pollen-heavy calendar amplified by humidity, mold pressure, and significant seasonal overlap.
