How to connect?

The vegetation around Door County, on a narrow peninsula between Lake Michigan and Green Bay, is dominated by northern white cedar and sugar maple, with cherry orchards adding further seasonal pollen exposure. Wind patterns across the area help determine how far pollen travels from these source plants. The mix of native and introduced species here is fairly typical for this part of the country.

How often is the Door County pollen forecast updated?

Does pollen in Door County 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 Door County 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 Door County, 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.
