Passaic's northern New Jersey Passaic River setting features oak, maple, and sweetgum as the main tree pollen sources, with exposure varying between the limited wooded residential areas and the more built-up industrial and commercial corridors. The Passaic River corridor provides the most significant local green space, while the dense urban New Jersey setting means most pollen is carried in from surrounding greener suburban areas throughout the season.

How often is the Passaic pollen forecast updated?

Does pollen in Passaic 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 Passaic 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 Passaic, 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.
