The vegetation around Mackinac Island, on a small limestone island in the Straits of Mackinac, is dominated by northern white cedar and paper birch, with wild lilac (the island's namesake bloom) adding further seasonal pollen exposure. Local parks and open ground tend to see higher pollen counts than the denser urban core. Microclimates within the area can shift the timing slightly from one neighborhood to the next.

Does pollen in Mackinac Island 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 Mackinac Island 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 Mackinac Island, 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.
