When is pollen season in Duluth?
Duluth's regional pollen pattern holds at Lake Superior Zoo, with elm and cottonwood first appearing in March with ash joining in and continuing through April. Grass pollen builds through May and June, and ragweed and mugwort extend the season into September. The continental climate and surrounding farmland drive a well-defined spring tree peak and a strong late-summer ragweed season, which shapes conditions at Lake Superior Zoo much as it does elsewhere in Duluth.
How often is the Duluth pollen forecast updated?

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

Does pollen in Duluth 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 Duluth 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 Duluth, 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.
