Sterling Heights' suburban setting in Macomb County features oak, birch, and maple as the main tree pollen sources in parks and along residential streets, with exposure varying between these green areas and the more built-up areas. Surrounding Michigan farmland and woodland contribute substantial grass and tree pollen, while the flat, open landscape allows pollen to disperse readily across the city under prevailing westerly winds.

Does pollen in Sterling Heights 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 Sterling Heights 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 Sterling Heights, 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.
