New Brunswick's Raritan River New Jersey setting features oak, tulip poplar, and maple as the main tree pollen sources, with exposure varying between the Rutgers University campus woodland and the more built-up downtown commercial and medical corridor along George Street. The Raritan River corridor and Rutgers University Cook Campus are particularly significant local sources, while the university arboretum and extensive campus green spaces create distinct pollen gradients between the campus and the urban downtown core.

How often is the New Brunswick pollen forecast updated?

Does pollen in New Brunswick 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 New Brunswick 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 New Brunswick, 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.
