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 Syracuse 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 12.6% of adults in the city of Syracuse have current asthma, according to the CDC’s PLACES estimate for 2023 (95% confidence interval: 11.3% to 14.0%). It is a statistical estimate from national survey data, not a count.
11 allergists enrolled in Medicare practice in the Syracuse area: 1.69 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 Syracuse area, or how every state and metro compares.

The geography, climate and plants behind each season here, with a source for every fact.
Close to 128 inches of snow falls at Syracuse’s airport in an average year.1 Winters average about 27 °F, and a typical year allows about 173 days between the last spring freeze and the first fall freeze.1
In 2007, a study of street tree decay randomly sampled 480 trees in each of four upstate cities: Albany, Buffalo, Rochester and Syracuse.2 The authors write that Norway, silver, sugar, red and other maples often make up over half of the street trees in New York State, in small communities and larger cities alike.2 The New York Flora Atlas lists Norway maple as not native but widely planted as a street tree, and notes that it naturalizes readily.3
Common ragweed is a widespread and common weed of farm fields, waste areas and gardens in New York.5 It generally flowers from August to October, starting once daylength drops to 14 hours or less.4 Salt-tolerant populations grow on roadsides that receive deicing salt in winter.4
Answered from the values on this page.
Very little. None of the plants Google models is above 0 in Syracuse today.
No. It’s Google’s modeled pollen index, from 0 (none) to 5 (very high), calculated for the location of central Syracuse. 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 Syracuse, 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.
