Nashville Pollen Report
Nashville sits in the Cumberland River basin, ringed by wooded hills — a geography that holds pollen and humidity over the city. Cedar and elm start the season early, oak dominates spring, grasses run through long humid summers, and ragweed owns the fall. Middle Tennessee's growing season is long, and so is its allergy calendar.

What drives allergies in Nashville
Trees: cedar, elm, and oak (February – May)
Eastern red cedar (Juniperus virginiana) and elm start in late winter; oaks (Quercus) take over as the dominant spring allergen through April and May.
Grasses: fescue and Bermuda (May – August)
Tennessee fescue pastures and Bermuda lawns pollinate heavily in early summer — June is typically the peak.
Weeds: ragweed (August – frost)
Middle Tennessee is strong ragweed country. Common ragweed (Ambrosia) fills field edges and roadsides, with counts elevated until a hard frost, often into November.
Mold: humid basin air
The Cumberland basin's humidity keeps Alternaria and Cladosporium active from late spring through fall, with spikes after storms.
