Greensboro Pollen Report
Greensboro anchors the Piedmont Triad in North Carolina's rolling hill country — dense with oak, pine, and hickory. 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 Triad's mild climate keeps the calendar running from February to November.

What drives allergies in Greensboro
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 and pasture grasses across the Triad pollinate through the long summer.
Weeds: ragweed (August – November)
Ragweed (Ambrosia) fills field edges and roadsides, with counts elevated until a late first frost.
Mold: humid Piedmont summers
Triad humidity keeps Alternaria and Cladosporium active from spring through fall.
