Pollen Count & Forecast for Memphis

Memphis’s spring allergy season (March-May) is dominated by Oak and Hickory pollen; Oak (Quercus) is prolific in Overton Park and Shelby Farms Park; Hickory (Carya) and Maple (Acer) are widespread along the Wolf River. Summer (May-July) sees elevated Bermuda Grass (Cynodon dactylon) levels; these originate from residential lawns and golf courses.

The Mississippi River valley traps allergens against the Chickasaw Bluffs; high humidity keeps pollen concentrations near the ground. Autumn and winter have high Mould (Alternaria, Cladosporium) counts; these spores come from damp leaf litter in the Old Forest State Natural Area and moisture along the Mississippi riverbanks.
