Pollen season in Georgia typically stops in late September or early October, though it can vary slightly by region.
- In North Georgia, pollen season usually ends by mid to late September due to cooler temperatures reducing pollen from weeds like ragweed and mold spores.
- In Metro Atlanta and Central Georgia, pollen season tends to end around late September to early October as cooler fall nights gradually suppress pollen production.
- South Georgia generally has the longest pollen season, which may extend into mid-October or even later in warmer years due to its humid climate supporting prolonged weed pollen and mold spore production.
Tree pollen is most prominent in spring and ends by late May, grass pollen peaks in summer, and weed pollen (especially ragweed) dominates late summer through fall, fading by late September or October with cooler weather.
