Piscataway's central New Jersey Raritan River setting features oak, sweetgum, and maple as the main tree pollen sources, with exposure varying between the wooded Rutgers University campus and the more built-up commercial corridors along New Brunswick Avenue. The Raritan River corridor and the Rutgers University Ecological Preserve are particularly significant local sources, while the university campus woodland creates distinct pollen gradients between the campus and the more built-up commercial areas.

When is pollen season in Piscataway?

Grass from surrounding New Jersey farmland peaks through June and July before mugwort and nettle extend exposure into September. The Raritan River valley channels airflows, while the moderate mid-Atlantic climate advances the season slightly compared to more northern New Jersey cities throughout.
How often is the Piscataway pollen forecast updated?

The Piscataway pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Piscataway 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 Piscataway 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 Piscataway, 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.
