Atlanta, Georgia sits in a valley surrounded by dense forests, creating a natural trap for pollen particles. The city's warm, humid subtropical climate enables one of the longest and most intense allergy seasons in the United States, running continuously from late February through October. This guide covers Atlanta's main pollen types, seasonal patterns, recent trends, and strategies to help you manage allergies year-round.
Understanding Pollen Count in Atlanta
Pollen count measures the concentration of pollen grains per cubic meter of air over a 24-hour period. In Atlanta, certified technicians at the only NAB-certified counting station manually identify pollen grains under microscopes to provide accurate daily counts. When pollen levels are high, common symptoms include sneezing, runny nose, itchy eyes, coughing, wheezing, and difficulty breathing.
Key Pollen Types and Record-Breaking Trends
Atlanta has experienced dramatic increases in pollen concentrations over the past three decades. On March 29, 2025, the city recorded its all-time highest pollen count of 14,801 grains per cubic meter due to multiple tree species blooming simultaneously combined with unseasonably warm February temperatures. All five of Atlanta's highest pollen counts on record have occurred since 2020, indicating a clear upward trend.
- Oak Pollen: The dominant tree allergen in Atlanta, peaking in late March to mid-April and contributing heavily to spring's extreme counts
- Pine Pollen: Major contributor to the visible yellow coating on cars and surfaces during spring, though less allergenic than oak
- Ragweed Pollen: The most notorious fall allergen, peaking in September and causing widespread allergic rhinitis throughout metro Atlanta
- Bermuda Grass Pollen: The most prevalent grass allergen, peaking in late May through June and bridging tree and weed seasons
Climate change has caused pollen seasons to start earlier each year, last longer, and produce higher concentrations. Between 1970 and 2024, Atlanta's freeze-free season increased by 36 days, allowing trees and plants to produce pollen over extended periods. Higher CO2 levels also make pollen more allergenic, compounding the health impact beyond just increased volume.
Atlanta's Year-Round Pollen Calendar
Atlanta experiences a continuous nine-month allergy cycle with distinct seasonal patterns:
- Late Winter to Spring (Late February to May): Dominated by tree pollen from oak, pine, birch, cedar, and maple, with April consistently showing the highest counts
- Late Spring to Summer (Late April to June): Grass pollen season overlaps with late tree pollen, featuring Bermuda grass, Timothy grass, and Kentucky Bluegrass peaking in June
- Summer to Fall (August to Late October): Weed pollen, particularly ragweed, peaks in September and causes widespread fall allergies across the metro area
- Winter (November to Early February): The only brief respite period, though mild winters can trigger early pollen release as soon as mid-January
