Santa Rosa's parks, including Howarth Park and the Santa Rosa Creek corridor, feature oak, eucalyptus, and madrone as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Sonoma County wine country and coastal grasslands contribute substantial grass and tree pollen, while onshore Pacific winds can periodically disperse urban pollen across the valley.

How often is the Santa Rosa pollen forecast updated?

Does pollen in Santa Rosa 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 Rosa 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 Rosa, 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.
