Knoxville Pollen Report
Knoxville sits in the Tennessee Valley at the foot of the Smokies — lush, humid, and consistently ranked among the toughest allergy cities in America. Oak and hickory bury the valley each spring, grasses run through the long summer, ragweed fills the fall, and the valley's humidity traps pollen and mold close to the ground for months.

What drives allergies in Knoxville
Trees: oak, hickory, and cedar (February – May)
Eastern red cedar starts as early as February; oak (Quercus) and hickory follow, with April the peak of a heavy tree season.
Grasses: fescue and Bermuda (April – September)
Tall fescue pastures and Bermuda lawns keep grass pollen aloft through the long, humid summer.
Weeds: ragweed (August – November)
Ragweed (Ambrosia) fills the valley's field edges and roadsides, with counts elevated until a late first frost.
Mold: valley humidity
The Tennessee Valley's humid climate and river corridors keep Alternaria and Cladosporium active most of the year.
