Beyond today’s pollen
What this forecast doesn’t measure, and when to get help.
No mold level
Google’s index covers tree, grass and weed pollen only, so there is no mold level for Sacramento 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.
No indoor allergens
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.
Asthma in Sacramento
An estimated 10.2% of adults in the city of Sacramento have current asthma, according to the CDC’s PLACES estimate for 2023 (95% confidence interval: 9.1% to 11.4%). It is a statistical estimate from national survey data, not a count.
Allergists in the Sacramento area
39 allergists enrolled in Medicare practice in the Sacramento area: 1.57 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 Sacramento area, or how every state and metro compares.

Sacramento’s pollen seasons
The geography, climate and plants behind each season here, with a source for every fact.
The Sacramento Valley’s north-south lie and the Sierra Nevada turn the ocean wind that enters through the Carquinez Strait, giving Sacramento a southerly prevailing wind all year.2 Mountains surround the valley to the west, north and east.2 A typical year brings about 341 days between the last spring freeze and the first fall freeze, and summers average about 76 °F.1
The city’s public tree inventory counted 87,324 trees in 2018, and London planetree made up 15.5 percent of them.3 Valley oak (Quercus lobata) made up about 4 percent, and Modesto ash about 2 percent.3
Valley oak is found only in California, and it is wind pollinated, with catkins that emerge in March and April.4 Fremont cottonwood is considered an important member of the Sacramento Valley’s climax streamside vegetation.5 It generally first flowers early in spring, before its leaves emerge, and finishes by the end of May; its flowers are entirely wind pollinated.5
