Roswell, Georgia, located in the humid subtropical Piedmont region of metro Atlanta, experiences one of the longest and most intense pollen seasons in the United States. With a 9-month continuous allergy season running from February through October, residents face year-round challenges from tree, grass, and weed pollen. This guide provides essential information about pollen types, seasonal patterns, recent trends, and effective management strategies to help you navigate Roswell's demanding allergy environment.
Understanding Pollen Count in Roswell
Pollen count measures the concentration of pollen grains per cubic meter of air, indicating allergen exposure levels. In Roswell, counts are monitored by the National Allergy Bureau-certified station operated by Atlanta Allergy & Asthma, the only certified counting station in the Atlanta area. When pollen counts are high, common symptoms include sneezing, runny nose, itchy eyes, congestion, and asthma exacerbations, affecting approximately 20% of the population.
Key Pollen Types and Record-Breaking Trends in Roswell
Roswell's pollen landscape has intensified dramatically in recent years, with all five highest pollen counts recorded since 2020. The most severe peak occurred on March 29, 2025, when levels reached a staggering 14,801 grains per cubic meter. More recently, counts of 6,563 grains per cubic meter were recorded on March 23, 2026, demonstrating the ongoing severity of the region's allergy season.
- Oak Pollen: Comprises 41.1% of spring pollen and is the most allergenic tree species in Roswell
- Pine Pollen: Accounts for 28.1% of spring pollen, less allergenic but highly visible with yellow dust
- Ragweed Pollen: Dominant fall allergen peaking in mid-September, causing severe respiratory symptoms
- Bermuda Grass: Most common grass pollen type, overlapping with tree season in May for compounded allergic reactions
Climate change has significantly extended Roswell's pollen season, with Atlanta's freeze-free period increasing by 36 days between 1970 and 2024. This prolonged growing season allows pollen-producing plants to bloom earlier, last longer, and generate higher concentrations, creating unprecedented challenges for allergy sufferers in the region.
Seasonal Pollen Patterns in Roswell
Roswell experiences distinct pollen seasons throughout most of the year with only a brief winter respite.
- Spring (Late February to May): Dominated by tree pollen from oak, birch, pine, juniper, cedar, hickory, and maple, with peak counts often exceeding 1,500 grains per cubic meter in late March through mid-April
- Summer (Late April to June): Grass pollen season featuring Bermuda grass, Timothy grass, Kentucky Bluegrass, and Johnson grass, with May being particularly severe due to overlap with tree pollen
- Fall (August to November): Weed pollen season led by ragweed, pigweed, lamb's quarters, sagebrush, and nettle, peaking in mid-September until the first hard freeze in late November
- Winter (December): Brief respite period with minimal pollen activity before the cycle restarts in late January or early February
