SC pollen report
Columbia Pollen Report
Columbia sits where South Carolina's Sandhills meet the Piedmont, and its allergy seasons are long and hot. Pine and oak bury the metro in yellow dust each spring, grasses run through the famously humid summer — Columbia brands itself 'Famously Hot' — and ragweed fills the fall. River humidity along the Congaree keeps mold in play for months.

Frequently asked questions
What is the pollen count in Columbia, SC today?
PollyMap publishes real, microscope-verified pollen counts for Columbia — 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 Columbia right now?
Columbia'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 Columbia, SC?
February through November: trees in spring, grasses through the long hot summer, ragweed in the fall, and mold through the humid months.
Why does the yellow pollen coating Columbia each spring not match my symptoms?
The visible yellow dust is pine pollen — large, sticky, and mild. The oak and hickory pollen released at the same time is invisible and drives most symptoms.
Is pollen still bad in Columbia in the fall?
Yes. Ragweed peaks across the Midlands in September and October, and damp fall conditions keep mold spores elevated. The season usually runs until the first frost in November.
