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 Toledo 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 12.1% of adults in the city of Toledo have current asthma, according to the CDC’s PLACES estimate for 2023 (95% confidence interval: 10.9% to 13.5%). It is a statistical estimate from national survey data, not a count.
6 allergists enrolled in Medicare practice in the Toledo area: 1.00 for every 100,000 people, fewer 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 Toledo area, or how every state and metro compares.

The geography, climate and plants behind each season here, with a source for every fact.
Sand carried by glacial meltwater, then moved by offshore currents into closely aligned beach ridges, underlies the Oak Openings of Lucas, Henry and Fulton counties.2 Historically, white oak and black oak were the dominant trees on its upland ridges and dunes, where grasses such as little bluestem, big bluestem and Indian grass were common.2 Today nearly all the areas that remain natural are much more heavily forested, and urbanization has removed most of the natural vegetation in the region’s northeastern fifth.2
Northwest Ohio has a mainly continental climate, though the Toledo area, near Lake Erie, sees some lake effect during easterly winds.3 At Toledo Express Airport, a typical year has about 188 days between the last spring freeze and the first fall freeze, and about 35 inches of precipitation.1
An Ohio State University Extension sheet notes that two species of ragweed grow in Ohio, common and giant.4 It says ragweed usually starts blooming in August and goes through November, with September the highest pollen month.4
Answered from the values on this page.
Very little. None of the plants Google models is above 0 in Toledo today.
No. It’s Google’s modeled pollen index, from 0 (none) to 5 (very high), calculated for the location of central Toledo. 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 Toledo, 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.
