Redmond's Puget Sound suburban setting features alder, bigleaf maple, and Douglas fir as the main tree pollen sources, with exposure varying between the extensively forested residential hillsides and the more built-up technology corridor along State Route 520. The Sammamish River corridor and the Bear Creek corridor are particularly significant local sources, while the forested hillsides contribute substantially more tree pollen than the developed valley floor.

How often is the Redmond pollen forecast updated?

Does pollen in Redmond 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 Redmond 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 Redmond, 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.
