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 Burlington 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 11.8% of adults in the city of Burlington have current asthma, according to the CDC’s PLACES estimate for 2023 (95% confidence interval: 10.6% to 13.1%). It is a statistical estimate from national survey data, not a count.
1 allergist enrolled in Medicare practices in the Burlington area: 0.44 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 Burlington area, or how every state and metro compares.

The geography, climate and plants behind each season here, with a source for every fact.
Lake Champlain moderates western Vermont, which sees higher temperatures and a longer growing season than the more mountainous Northeast Kingdom.2 A typical year at Burlington’s airport allows about 169 days between the last spring freeze and the first fall freeze.1 About 88 inches of snow falls in an average year.1

The Vermont Department of Health’s Environmental Public Health Tracking Program publishes tree, grass, weed and ragweed pollen data in collaboration with a pollen counting station in Vermont.5 Pollen is counted from about March to October each year, and the published data run from 2009 through 2024.5
Answered from the values on this page.
Very little. None of the plants Google models is above 0 in Burlington today.
No. It’s Google’s modeled pollen index, from 0 (none) to 5 (very high), calculated for the location of central Burlington. 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 Burlington, 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.
