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 Los Angeles 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 9.4% of adults in the city of Los Angeles have current asthma, according to the CDC’s PLACES estimate for 2023 (95% confidence interval: 8.5% to 10.4%). It is a statistical estimate from national survey data, not a count.
182 allergists enrolled in Medicare practice in the Los Angeles area: 1.42 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 Los Angeles area, or how every state and metro compares.

The geography, climate and plants behind each season here, with a source for every fact.
Without a freeze in a typical year, downtown Los Angeles averages about 58 °F in winter.1 Coast live oak grows along California’s Coast, Transverse and Peninsular ranges, from sea level to 5,000 feet in the southern part of the state.2 The tree is wind pollinated, and its catkins emerge in March and April.2 In the Santa Monica Mountains, a National Park Service project tracks when coast live oak, valley oak and four other plants flower, at monitoring sites along hiking trails.3
California sagebrush, the most important and widely distributed plant of coastal sage scrub, grows in both coastal and inland Los Angeles County.4 It is wind pollinated, and its reported flowering times vary with elevation and location.4 Bermuda grass grows throughout California outside the Great Basin, up to about 2,900 feet, and blooms from June through September.5
Answered from the values on this page.
Very little. None of the plants Google models is above 0 in Los Angeles today.
No. It’s Google’s modeled pollen index, from 0 (none) to 5 (very high), calculated for the location of central Los Angeles. 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 Los Angeles, so each day starts with its own values, and again after Google’s daily model run, usually by about 7:30 am PT. 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.
