AL pollen report
Birmingham Pollen Report
Birmingham spreads across the ridges and valleys of the southern Appalachians — and it's routinely ranked among America's toughest allergy cities. Oak and pine bury the metro each spring, grasses run through the long, humid summer, ragweed fills the fall, and the region's rainfall keeps mold active for months. The calendar runs from February into November.

What drives allergies in Birmingham
Trees: oak, pine, and hickory (February – May)
Oak (Quercus) and pine dominate the forested ridges; hickory and sweetgum contribute. March and April are the peak.
Grasses: Bermuda and fescue (April – September)
Lawn and pasture grasses keep pollen aloft through the long, humid summer.
Weeds: ragweed (August – November)
Ragweed (Ambrosia) thrives across the region's field edges, with counts elevated until a late first frost.
Mold: one of the wettest big cities in America
Birmingham gets more annual rainfall than Seattle — Alternaria and Cladosporium stay active through the warm months, with spikes after storms.
