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 Lexington 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.
18 allergists enrolled in Medicare practice in the Lexington area: 3.36 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 Lexington area, or how every state and metro compares.

The geography, climate and plants behind each season here, with a source for every fact.
Minerals in the Lexington Limestone act as natural fertilizers, building up in the soil and supporting the region’s agriculture and its “blue” grass.2 Fayette County lies within the Inner Blue Grass, a landscape of gently rolling hills over limestone and shale.2 About 50 inches of precipitation falls at Blue Grass Airport in an average year, and a typical year has about 196 days between the last spring freeze and the first fall freeze.1
Lexington has more than 53,000 street trees, with ash, oak, pear, maple and sycamore among the common species.3 Across Kentucky, tall fescue, orchardgrass and Kentucky bluegrass are the most widely sown cool-season perennial grasses for forage, followed by timothy.4
Common ragweed, a summer annual, turns up in pastures and crops throughout the United States when not managed.5 University of Kentucky weed scientists call its pollen a major contributor to fall hay fever among Kentucky residents.5
Answered from the values on this page.
Very little. None of the plants Google models is above 0 in Lexington today.
No. It’s Google’s modeled pollen index, from 0 (none) to 5 (very high), calculated for the location of central Lexington. 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 Lexington, 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.
