TN pollen report
Chattanooga Pollen Report
Chattanooga has ranked among the toughest allergy cities in the South, and its geography explains it: a Tennessee River valley ringed by wooded mountains that hold pollen and humidity over the city. Oak and hickory bury the ridges each spring, grasses run through long humid summers, and ragweed fills the valley every fall.

What drives allergies in Chattanooga
Trees: oak, hickory, and cedar (February – May)
Eastern red cedar and elm start in late winter; the surrounding mountains' oak-hickory forest (Quercus, Carya) dominates April.
Grasses: fescue and Bermuda (May – August)
Lawn and pasture grasses pollinate heavily in early summer across the valley, with June the typical peak.
Weeds: ragweed (August – November)
Ragweed (Ambrosia) thrives along the river and in the valley's disturbed soils, with counts elevated until a hard frost.
Mold: the valley's humid constant
The river valley's muggy air keeps Alternaria and Cladosporium active from spring through late fall, with spikes after the region's frequent storms.
Pollen patterns in Chattanooga
