Atlanta Pollen Season: When It Peaks and What It Does to Gutters

Going by the Atlanta Allergy & Asthma count, the area’s National Allergy Bureau certified station, daily totals first passed 100 on February 7 in 2025 and February 11 in 2026. The heaviest days usually land between March 20 and April 13, and the last day over 1,000 came on April 16, 2025 and April 15, 2026. By the final week of April both years, counts were back under 200.

Late April or early May, once the oak tassels have fallen and the daily count has dropped off. Cleaning in the middle of the peak only buys a few days, because the next yellow layer and the next round of tassels refill the trough. Clearing it after the drop, before summer thunderstorms, means the first big downpour runs to the outlets instead of over the front edge.

On its own, the dust mostly washes through. The trouble starts when rain carries it into a gutter already holding oak tassels and pine needles. The pollen binds that debris into a dense, wet mat that slows or blocks the outlet. In Gwinnett, North Fulton and Athens area yards under heavy oak and pine, that mat is often what causes the first overflow of the year.

No guard stops every grain of pollen, and we will not tell you otherwise. What BroGuard stainless micro-mesh does is keep oak tassels, pine needles and sweetgum balls on top of the gutter, so the fine dust has nothing to bind to and most of it rinses through in the next rain. Where Atlanta pines hang over the roof, our pine needle guards add the finer mesh those lots need.

Atlanta Allergy & Asthma posts the daily count on its website at atlantaallergy.com/pollen_counts, with a calendar of past months. It reports the number of pollen grains in a cubic meter of air over the previous 24 hours and names the top tree, grass and weed contributors. Its counting station is the only one in the Atlanta area certified by the National Allergy Bureau.
