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 Erie 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.
3 allergists enrolled in Medicare practice in the Erie area: 1.13 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 Erie area, or how every state and metro compares.

The geography, climate and plants behind each season here, with a source for every fact.
Once cooled by winter, Lake Erie keeps springs cool in the grape country along its Pennsylvania shore, preventing early bud break and frost damage.2 Warmed by the summer sun, the lake keeps the soil warmer in fall and extends the growing season.2 About 104 inches of snow falls at Erie’s airport in a typical year, and about 192 days pass between the last spring freeze and the first fall freeze.1
At Pennsylvania’s western end, the Great Lakes beech–sugar maple forest counts tuliptree, sugar maple, beech, basswood and red oak among its common trees.3 Swamp forests along Lake Erie are the only places in the state where pumpkin ash occurs.3
Curly dock, a weed whose pollen is spread by wind, occurs throughout Ohio and surrounding states.4 Its flowers appear in May and can continue into October and November.4 Across Pennsylvania, ragweed pollen dispersal generally peaks in the last week of August and the first week of September.5
Answered from the values on this page.
Very little. None of the plants Google models is above 0 in Erie today.
No. It’s Google’s modeled pollen index, from 0 (none) to 5 (very high), calculated for the location of central Erie. 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 Erie, 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.
