Saugatuck sits on the dune country along the Kalamazoo River mouth on Lake Michigan, where the dominant vegetation is a mix of dune grass and cottonwood, northern hardwood forest, and coastal juniper, shaping the local pollen profile across the seasons. Seasonal timing here follows the broader regional pattern typical of this part of the country. Microclimates within the area can shift the timing slightly from one neighborhood to the next.

Does pollen in Saugatuck 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 Saugatuck 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 Saugatuck, 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.
