What this forecast doesn’t measure, and when to get help.
Google’s index covers tree, grass and weed pollen only, so there is no mold level for Chattanooga 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.
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.
An estimated 11.6% of adults in the city of Chattanooga have current asthma, according to the CDC’s PLACES estimate for 2023 (95% confidence interval: 10.4% to 12.9%). It is a statistical estimate from national survey data, not a count.
13 allergists enrolled in Medicare practice in the Chattanooga area: 2.19 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 Chattanooga area, or how every state and metro compares.

The geography, climate and plants behind each season here, with a source for every fact.
Climate zones in Chattanooga step from Zone 7 in the valleys to Zone 6 on the mountaintops, the city’s urban forestry plan notes.2 Water-loving trees such as sycamore, river birch, cottonwood, willow and elm grow along the banks and lowlands of the Tennessee River and its tributaries.2 A dry ridge and upland system holds pines, maples, hickory and oaks.2 At the airport, winters average about 44 °F, and about 55 inches of precipitation falls in a typical year.1
The plan estimates that the city is responsible for over 204,000 street trees.2 Hackberry is the most common at 10.8% of them, ahead of flowering dogwood at 7.5% and red maple at 4.9%.2 As of 2008, tree canopy covered 51.4% of the city.2
The city’s plan names privet among the invasive exotic plants that thrive in the area, along with kudzu, English ivy, mimosa and shrub honeysuckle.2 Chinese privet, introduced to the United States as an ornamental, appears on the Tennessee Exotic Pest Plant Council’s list, and the species flowers from April to June.3
Answered from the values on this page.
No. The highest level in Chattanooga today, Tuesday, November 3, is very low (1 on the 0 to 5 index), led by ragweed. Weed pollen is very low.
According to Google’s model: Ragweed (very low). Plants Google doesn’t model, and mold, aren’t included.
No. It’s Google’s modeled pollen index, from 0 (none) to 5 (very high), calculated for the location of central Chattanooga. A pollen count is the number of pollen grains measured in a cubic meter of air at a counting station. How our pollen index works.
Twice a day. We fetch new values soon after midnight in Chattanooga, so each day starts with its own values, and again after Google’s daily model run, usually by about 10:30 am ET. Each section shows when its values were retrieved.
Since October 14, 2026. The year in pollen above fills in as each day is recorded, and weeks before then show no data. Google doesn’t provide past values, so nothing earlier can be added.
