Beyond today’s pollen
What this forecast doesn’t measure, and when to get help.
No mold level
Google’s index covers tree, grass and weed pollen only, so there is no mold level for Nashville on this page. The National Allergy Bureau publishes pollen and mold counts measured at its stations. Our guides cover common molds such as Alternaria, Cladosporium and Aspergillus.
No indoor allergens
The forecast doesn’t cover allergens indoors either: dust mites, cockroaches, mice, cats and dogs. Our guides explain each one, starting with dust mites and cats.
Asthma in Nashville
An estimated 10.8% of adults in the city of Nashville have current asthma, according to the CDC’s PLACES estimate for 2023 (95% confidence interval: 9.5% to 12.1%). It is a statistical estimate from national survey data, not a count.
Allergists in the Nashville area
47 allergists enrolled in Medicare practice in the Nashville area: 2.14 for every 100,000 people, more than the 1.22 across the US. The count doesn’t show how soon you can get an appointment. See the doctors listed in the Nashville area, or how every state and metro compares.

Nashville’s pollen seasons
The geography, climate and plants behind each season here, with a source for every fact.
Limestone outcrops and shallow soils are common across Tennessee’s Central Basin, a moderately rolling region surrounded by the Highland Rim.2 Davidson County lies in the basin’s northwestern part.2 At the airport, winters average about 42 °F, and a typical year has about 217 days between the last spring freeze and the first fall freeze.1
Before European settlement, the county was entirely forested, and upland oak species made up two-thirds of the forest’s volume.2 Today eastern redcedar is the county’s dominant conifer, and its pure stands typically grow where soil is shallow over limestone.2 The Central Basin’s limestone cedar glades are patches of very thin soil and exposed rock surrounded by redcedar trees.3 Across its range, eastern redcedar pollinates from February in the south and east to May in the north and west.4
Giant ragweed, which can grow more than 16 feet tall, is readily found along fence rows of crop fields and pastures in Tennessee.5 It also grows in low woods, along creeks and railroads, and in waste areas, and it thrives in moist soil and full sun.5
