Local Environmental Conditions
Around 50% of the area near this location in Dearborn Heights is built-up land, with a good deal of woodland and some open grassland. Lawns and planted trees in a nearby park add to local grass and tree pollen. Trees are an important local pollen source, given how much woodland surrounds the area. Among weeds, ragweed stands out as local pollen source.
Tree pollen comes first, peaking in mid-spring. Ragweed brings a final peak from late summer into mid-fall. By late fall, as temperatures fall to around 5°C, pollen levels are low again. Day to day, sunshine and wind lift the counts, while a spell of rain can bring them down sharply.

How often is the Dearborn Heights pollen forecast updated?

Does pollen in Dearborn 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 Dearborn 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 Dearborn 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.

Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
