Hendricks Park sees the same pollen timeline as the rest of Eugene, beginning with alder and birch in February with maple taking the lead through March and April. Grass pollen builds through May and June, and dock and mugwort keep weed pollen elevated into September. Frequent spring rain across the Pacific Northwest periodically clears pollen from the air, moderating peak counts, which shapes conditions at Hendricks Park much as it does elsewhere in Eugene.

The Eugene 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 Eugene, 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.
