Tree pollen is the primary allergy trigger in Georgia right now. As of early March, the dominant culprits are juniper, pine, elm, and maple trees, with a total pollen count of 49, which falls in the moderate range (15–89). Nettle weed is also contributing at low levels, and mold activity is present but not yet elevated.
The Trees Driving Your Symptoms
Georgia’s tree pollen season runs from late February through May, and it’s just getting started. Right now, four species are producing the most pollen: juniper (often called cedar), pine, elm, and maple. Of these, juniper is one of the earliest and most potent triggers. Its fine, wind-carried pollen can travel for miles and is a common cause of the sneezing, congestion, and itchy eyes many Georgians are already experiencing.
Pine pollen gets the most attention because it’s visible. It coats cars, driveways, and outdoor furniture in a thick yellow-green dust. But despite its dramatic appearance, pine pollen grains are actually too large to penetrate deep into the airways for most people. The smaller, invisible grains from juniper, elm, and maple are more likely to cause true allergic reactions. So if your car looks clean but your nose is running, those less visible pollens are probably to blame.
The count will climb significantly in the coming weeks. Moderate days in early March often give way to high and extremely high counts by late March and April, when oak and hickory trees join the mix. Georgia’s pollen scale tops out at 1,500 or more for trees, a level the Atlanta area hits multiple times each spring. The worst is still ahead.
Why This Season May Hit Hard
A cold snap and snowfall earlier this year pushed Georgia’s allergy season start date back slightly. But a delayed start doesn’t mean a mild season. According to biologist Dr. Harvey at Georgia Southern University, cold weather can actually make the eventual bloom more intense, as trees that held off on pollinating release it in a compressed burst once temperatures warm.
The broader trend is also working against allergy sufferers. Rising temperatures and higher carbon dioxide levels are making Georgia’s pollen seasons longer and more intense year over year. Warmer weather lets plants start producing pollen earlier, ramp up their output faster, and keep going later into the season. The result is more total pollen over a longer stretch of months. If your allergies feel worse than they did a decade ago, they probably are.
How Rain and Humidity Factor In
Rain is a double-edged sword for Georgia allergies. In the short term, a good downpour washes pollen out of the air and can provide a few hours of relief. Studies consistently show that daily pollen counts drop on rainy days across trees, grasses, and weeds. But the relief is temporary. Rainfall also promotes plant growth, which means more pollen production in the days that follow once things dry out. A stretch of rain followed by warm, sunny weather is essentially a recipe for a pollen explosion.
Georgia’s humidity also feeds mold growth. The most common allergenic outdoor molds in the state include Cladosporium, Aspergillus, and Penicillium species. Mold activity is currently low to moderate, but as spring humidity builds, especially in southern Georgia and coastal areas, mold spore counts tend to rise. If your symptoms persist on low-pollen days, mold may be a contributing factor.
What’s Coming Next
Georgia’s allergy calendar unfolds in three overlapping waves. Tree pollen dominates from now through May. Grass pollen, primarily from Bermuda and other warm-season grasses, picks up in late April and peaks through June. Then ragweed and other weeds take over from August through October, with ragweed pollen capable of traveling hundreds of miles on the wind and persisting well into fall.
For the next several weeks, tree pollen will be the main issue. The practical advice is straightforward: check daily pollen counts (Atlanta Allergy & Asthma publishes them each morning), keep windows closed on moderate and high days, and shower after spending time outdoors to rinse pollen off your skin and hair. Symptoms tend to be worst in the early morning hours when pollen counts peak, so timing outdoor exercise for later in the day can help. Over-the-counter antihistamines and nasal steroid sprays are the standard first line of defense, and starting them before your symptoms become severe makes them more effective.
