When is pollen season in Olympia?
Like the rest of Olympia, Washington State Capitol experiences a season that opens with alder and birch from February then maple follows, running through March and April. Grass pollen rises through May and June, and plantain and nettle stretch the season into September. The damp, mild regional climate keeps pollen counts lower than in drier parts of the country, though spring rain events can trigger brief spikes throughout the year.
How often is the Olympia pollen forecast updated?

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

Does pollen in Olympia 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 Olympia 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 Olympia, 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.
