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 Columbus 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 11.7% of adults in the city of Columbus have current asthma, according to the CDC’s PLACES estimate for 2023 (95% confidence interval: 10.5% to 12.8%). It is a statistical estimate from national survey data, not a count.
38 allergists enrolled in Medicare practice in the Columbus 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 Columbus area, or how every state and metro compares.

The geography, climate and plants behind each season here, with a source for every fact.
Maples account for 33% of the 4,563 street trees inventoried in Columbus’s University District in 2022, and sugar maple is the most abundant species.2 By genus, oaks make up 8% of those trees and elms 6%.2
A typical year at the airport brings about 191 days between the last spring freeze and the first fall freeze.1 About 42 inches of rain and other precipitation falls in an average year.1
In Ohio, wild eastern cottonwoods commonly grow near streams and rivers, and their pollen drifts on the wind in early spring.3 Tall fescue, a grass found throughout Ohio, flowers between May and June.4 Ragweed follows in late summer, usually starting to bloom in August and continuing into November.5 Its highest pollen month is September.5
Answered from the values on this page.
Very little. None of the plants Google models is above 0 in Columbus today.
No. It’s Google’s modeled pollen index, from 0 (none) to 5 (very high), calculated for the location of central Columbus. 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 Columbus, 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.
