Kirkland's parks and the Lake Washington eastern shoreline corridor feature alder, birch, and Douglas fir as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding King County woodland and the Cascade Mountain foothills contribute substantial tree and grass pollen, while the lake position means onshore breezes can periodically disperse urban pollen.

How often is the Kirkland pollen forecast updated?

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

Does pollen in Kirkland 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 Kirkland 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 Kirkland, 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.
