Lacey's Puget Sound suburban setting in Washington produces a season opening in January with alder before birch peaks through March and April. Grass from surrounding Pacific Northwest land peaks through June and July before mugwort and nettle extend exposure into September. The wet Pacific oceanic climate provides very frequent rainfall interruptions throughout, while the South Puget Sound position means slightly more continental conditions than in northern Puget Sound cities.

The Lacey 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 Lacey, 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.
