Union City's Hudson County New Jersey waterfront setting features oak, sweetgum, and maple as the main tree pollen sources, with exposure varying between the limited green residential areas on the Palisades ridge top and the more built-up commercial corridors below. The Palisades ridge creates a distinct elevation-based pollen gradient between the ridge top and the Hudson waterfront below, while the urban setting means most pollen is carried in from surrounding greener areas.

Does pollen in Union City 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 Union City 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 Union City, 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.
