Pollen Count & Forecast for Atlanta

Atlanta’s spring allergy season (March-May) is dominated by Oak and Pine pollen; Oak (Quercus) prolific in Piedmont Park and Grant Park; Pine (Pinus) widespread across Buckhead neighborhoods. Sweetgum (Liquidambar styraciflua) and Hickory (Carya) increase counts near the Chattahoochee River. Summer and autumn (June-October) see high Bermuda Grass (Cynodon dactylon) and Ragweed (Ambrosia) pollen levels, originating from open fields and along BeltLine trails.

Dense tree canopies and humid air trap particulates; the urban heat island effect extends the growing season. Autumn and winter see high Mould (Alternaria, Aspergillus) spore counts, from damp leaf litter in the Fernbank Forest and wooded suburban areas.
