SC pollen report
Greenville Pollen Report
Greenville sits in the South Carolina Upstate, where the Blue Ridge foothills meet the Piedmont — one of the Southeast's most allergy-intense regions. Pine and oak coat the metro each spring, grasses run through long humid summers, and ragweed is heavy from August to frost. The warm season is long, and so is the allergy calendar.

What drives allergies in Greenville
Trees: pine, oak, and hickory (February – May)
Loblolly pine produces the visible yellow coating each spring, while oak (Quercus) and hickory deliver the heavier allergy load at the same time. March and April are the peak.
Grasses: Bermuda and fescue (April – September)
Lawn and pasture grasses pollinate through a long Upstate summer, with June typically the worst month.
Weeds: ragweed (August – November)
Ragweed (Ambrosia) fills roadsides, fields, and the fast-growing metro's construction corridors. Counts stay elevated until a hard frost.
Mold: humid Piedmont air
Upstate humidity keeps Alternaria and Cladosporium active from spring through fall, with spikes after summer storms.

Frequently asked questions
What is the pollen count in Greenville, SC today?
PollyMap publishes real, microscope-verified pollen counts for Greenville — measured from physical air samples. The latest report on this page shows current tree, grass, weed, and mold levels.
Is the pollen count high in Greenville right now?
Greenville's worst stretches are March–April (pine, oak), June (grasses), and September–October (ragweed). The measured reports on this page show today's actual levels.
When is allergy season in Greenville, SC?
February through November: trees in spring, grasses through the long summer, ragweed in the fall, and mold through the humid months.
Is the yellow spring pollen in Greenville what causes allergies?
Mostly no. The yellow dust is pine pollen — large, mild grains. The oak and hickory pollen released at the same time is invisible and far more allergenic.
Is pollen still bad in Greenville in the fall?
Yes. Ragweed peaks in the Upstate through October, and fall leaf litter in the foothills drives mold counts up. Greenville's season typically runs until the first frost in late October or November.
