On 16 July 2026, Grass is the dominant pollen source in Everett. alder, ambrosia, artemisia, birch, cypress, oak, and willow are not currently active.

Everett's pollen season in Washington opens with alder from January, followed by birch and Douglas fir through March and April. Grass pollen peaks through June and July. The Puget Sound coastal position means onshore winds can periodically disperse pollen, while surrounding Snohomish County woodland and the Cascade Mountain foothills contribute substantial tree pollen. Frequent Pacific Northwest rainfall provides regular interruptions throughout the season.

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

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.

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 Everett, 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.
