Pollen Count & Forecast for Nashville
About Pollen in Nashville
Nashville’s spring allergy season (March-May) is dominated by Cedar and Oak pollen; Eastern Red Cedar (Juniperus virginiana) prolific in Warner Parks; Oak (Quercus) widespread in Centennial Park. Hickory (Carya) contributes significantly from Shelby Bottoms. Summer (May-July) sees high Grass (Poaceae) pollen levels, originating from lawns and along Cumberland River riverbanks.
The Nashville Basin and Highland Rim hills trap pollen, leading to localised high concentrations. Autumn sees elevated Mould (Alternaria, Cladosporium) spore counts, from decaying leaves in Radnor Lake State Park and damp garden environments.
