Jersey City's pollen season opens with maple and birch from late February, followed by oak and cherry through April and May.

As part of the greater New York metropolitan area, the season is well-defined and intense, while surrounding New Jersey woodland and farmland contribute additional grass and tree pollen under prevailing westerly winds.

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.

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 Jersey 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.
