Arlington Heights's Chicago suburban setting features oak, maple, and elm as the main tree pollen sources, with exposure varying between the numerous parks and tree-lined residential streets and the more built-up commercial corridors. Salt Creek provides locally significant green space, while the flat Midwest landscape allows pollen to disperse widely and the substantial residential tree canopy makes this one of the more significant tree pollen locations in the Chicago northwestern suburbs.

Does pollen in Arlington 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 Arlington 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 Arlington 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.
