Local Environmental Conditions
This location in Harbor Beach sits in a varied landscape of woodland, open water and farmland. A nearby park adds mown lawns and planted trees to the local pollen mix. In the immediate area, the surrounding woods make trees an important source; open grassland and farmland add grass and weed pollen.
Tree pollen comes first, peaking in late spring. Grass pollen follows, peaking in early summer and easing off by early fall. Weeds on open ground add a smaller late peak from early summer into early fall. By late fall, as temperatures fall to around 5°C, pollen levels are low again.

Does pollen in Harbor Beach 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 Harbor Beach 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 Harbor Beach, 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.
