Raleigh Pollen Report
Raleigh locals have a word for it: the 'pollening' — the weeks each spring when pine pollen turns cars, porches, and puddles across the Triangle bright yellow. But the visible pine is only part of the story: oak, hickory, and birch release the smaller grains that drive most symptoms, and Raleigh's long warm season keeps grasses, ragweed, and mold going deep into fall.

What drives allergies in Raleigh
Trees: pine, oak, and hickory (February – May)
Loblolly pine (Pinus taeda) produces the famous yellow coating, while oak, hickory (Carya), and birch deliver the heavier allergy load at the same time. Peak season is March and April.
Grasses: Bermuda and fescue (May – August)
Lawn grasses take over as trees fade, peaking in early summer across the Triangle's yards and parks.
Weeds: ragweed (August – November)
Ragweed (Ambrosia) dominates the fall along roadsides, greenways, and construction sites — abundant in a fast-growing metro.
Mold: humidity nearly year-round
Piedmont humidity keeps Alternaria and Cladosporium active from spring through fall, with spikes after summer storms and during damp autumns.
Pollen patterns in Raleigh
In Raleigh, tree pollen — including Oak, Birch, Cedar — typically dominates from late winter through spring. Bluegrass grass is the most common warm-season pollinator, and Ragweed drives the largest fall pollen load.

Frequently asked questions
What is the pollen count in Raleigh today?
PollyMap publishes real, microscope-verified pollen counts for Raleigh — 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 Raleigh right now?
Raleigh's worst stretch is March and April, when pine and oak peak together. Ragweed drives a second wave from August through fall. The measured reports on this page show today's actual levels.
When is allergy season in Raleigh?
February through November: trees in spring (the yellow 'pollening'), grasses in summer, ragweed in fall, and mold through every humid stretch.
Is the yellow pollen in Raleigh what causes allergies?
Mostly no. The yellow dust is pine pollen — big, sticky grains that are mild allergens. The oak, hickory, and birch pollen released at the same time is invisible and far more reactive.
