Bartlett's DuPage and Cook County Illinois suburban setting features oak, maple, and elm as the main tree pollen sources, with exposure varying between the greener residential areas along Brewster Creek and the more built-up commercial corridors along Stearns Road. The Brewster Creek corridor and the Spring Creek Forest Preserve provide locally significant green space, while the flat Midwest landscape allows pollen to disperse widely and the numerous residential parks create distinct local pollen islands throughout.

How often is the Bartlett pollen forecast updated?

Does pollen in Bartlett 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 Bartlett 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 Bartlett, 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.
