Durham Pollen Report
Durham anchors one corner of the Research Triangle, in the heart of the North Carolina Piedmont's oak-and-pine country. Pine pollen coats the city each March, oak drives the real symptoms through April, grasses carry the humid summer, and ragweed fills the fall. The Triangle's mild climate keeps the calendar running from February into November.

What drives allergies in Durham
Trees: oak, pine, and hickory (February – May)
Loblolly pine produces the spring yellow coating; oak (Quercus) and hickory deliver the heavier allergy load. March and April are the peak.
Grasses: Bermuda and fescue (April – September)
Lawn grasses across the Triangle pollinate through the long summer.
Weeds: ragweed (August – November)
Ragweed (Ambrosia) fills the region's disturbed soils and construction edges, with counts elevated until a late first frost.
Mold: humid Piedmont summers
Triangle humidity keeps Alternaria and Cladosporium active from spring through fall.
