How to connect?

Santa Monica's coastal setting on the Pacific features eucalyptus, palm, and introduced oak as the main tree pollen sources in parks such as Palisades Park and along streets, with exposure varying between these green areas and the more built-up city centre. Strong onshore Pacific winds frequently disperse urban pollen, keeping exposure lower than in more sheltered inland parts of the Los Angeles basin.

When is pollen season in Santa Monica?
Santa Monica's pollen season opens with acacia and introduced olive from January in the mild Southern California coastal climate. Oak and grass follow through March and April, with the season peaking earlier than most US cities. Strong onshore Pacific winds from the Santa Monica Bay frequently disperse urban pollen, keeping coastal exposure among the lowest in the Los Angeles basin. The dry summer largely suppresses mid-season pollen along the coast.
How often is the Santa Monica pollen forecast updated?

The Santa Monica pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Santa Monica come from nearby or far away?

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Are pollen levels in Santa Monica based on measurements or forecasts?

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Santa Monica, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
