Cupertino's South Bay California setting features coast live oak, valley oak, and eucalyptus as the main tree pollen sources, with exposure varying between the wooded Stevens Creek corridor and Rancho San Antonio Open Space areas and the more built-up technology campus corridors along De Anza Boulevard. The Santa Cruz Mountain foothills concentrate pollen under certain downslope wind conditions, while the Stevens Creek corridor and reservoir area contribute particularly significant local tree pollen throughout spring.

Does pollen in Cupertino 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 Cupertino 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 Cupertino, 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.
