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 Ogden 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 11.6% of adults in the city of Ogden have current asthma, according to the CDC’s PLACES estimate for 2023 (95% confidence interval: 10.4% to 12.9%). It is a statistical estimate from national survey data, not a count.
8 allergists enrolled in Medicare practice in the Ogden area: 1.19 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 Ogden area, or how every state and metro compares.

The geography, climate and plants behind each season here, with a source for every fact.
Box elder, a maple native to Utah, bears its male and female flowers on separate trees.2 Its flowers bloom in March or April.2 Utah State University Extension calls Gambel oak the common scrub oak along the foothills of the Wasatch.3 In Utah, Gambel oak flowers usually appear in May or June, when the leaves are nearly half grown.4
About 16 inches of rain and other precipitation falls at the Ogden-Hinkley Airport in an average year.1 A typical year there has about 180 days between the last spring freeze and the first fall freeze.1
Late in the season, basin big sagebrush, a shrub whose range includes Utah, flowers from late August to October.5 Its flowers are pollinated by the wind or by their own pollen.5
Answered from the values on this page.
Very little. None of the plants Google models is above 0 in Ogden today.
No. It’s Google’s modeled pollen index, from 0 (none) to 5 (very high), calculated for the location of central Ogden. 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 Ogden, so each day starts with its own values, and again after Google’s daily model run, usually by about 8:30 am MT. 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.
