Pollen Count & Forecast for Raleigh
About Pollen in Raleigh
Raleigh’s spring allergy season (March-May) is dominated by Oak and Loblolly Pine pollen; Oak (Quercus) prolific in Pullen Park and downtown; Loblolly Pine (Pinus taeda) widespread in William B. Umstead State Park. Hickory (Carya) contributes significantly from forests along the Neuse River Trail. Summer and autumn (May-October) see high Grass (Poaceae) and Ragweed (Ambrosia) pollen levels, originating from fields near Yates Mill Pond.
Low-lying river basins and dense tree canopies can trap pollen, leading to localised high concentrations. Autumn and winter see elevated Mould (Alternaria, Cladosporium) spore counts, from decomposing leaf litter in the JC Raulston Arboretum and damp forest floors.
