Seaside's coastal setting on the Monterey Bay features oak, pine, and eucalyptus as the main tree pollen sources in parks and along streets, with exposure varying between these green areas and the more built-up city centre. Surrounding coastal grassland and the Fort Ord natural reserve contribute substantial grass and scrub pollen, while strong onshore Pacific winds frequently disperse urban pollen across the Monterey Peninsula.

How often is the Seaside pollen forecast updated?
The Seaside pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Seaside 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 Seaside 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 Seaside, 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.
