The allergy forecast in Nashville is mild today based on the supported tree, grass, and weed pollen data shown on this page.
Nashville sits in Middle Tennessee's humid subtropical climate zone, where mild winters, warm springs, and lengthy growing seasons create one of the more challenging allergy environments in the United States—the city is frequently ranked among the nation's worst metros for seasonal allergies.
Tree pollen launches the allergy calendar as early as February and peaks from March through April, with cedar and juniper starting the season, followed by heavy hitters like oak, maple, elm, hickory, sycamore, birch, and sweetgum, all abundant throughout the Cumberland Basin.
As tree pollen fades in May, grass pollen takes over, dominating late spring into midsummer; Bermuda, Timothy, fescue, orchard, and Johnson grass are the primary regional offenders, often peaking in June.
By mid-August, weed pollen becomes the main irritant, with ragweed leading through October, alongside lamb's quarters, pigweed, plantain, and sorrel.
Brief overlap periods—especially late spring (tree/grass) and early fall (grass/weed)—can intensify symptoms considerably.
Non-pollen triggers are also significant: Nashville's high humidity fuels year-round outdoor and indoor mold (particularly Alternaria and Cladosporium), while basin geography can trap dust, ozone, and vehicle pollution.
Overall, Nashville's allergy profile is defined by a long, overlapping pollen calendar compounded by persistent humidity-driven mold and stagnant air quality.
