Local Environmental Conditions
Cherry Hill's Delaware Valley New Jersey setting features oak, maple, and sweetgum as the main tree pollen sources, with exposure varying between the numerous residential green spaces and the more built-up commercial corridors. The Cooper River corridor provides locally significant green space, while the numerous suburban parks create distinct local pollen islands and the flat New Jersey landscape allows grass pollen to disperse widely.
Cherry Hill's Delaware Valley suburban setting in New Jersey produces a season opening in March with elm and maple before oak peaks through April and May. Grass from surrounding New Jersey and Pennsylvania farmland peaks through June and July before mugwort and nettle extend exposure into September. The Delaware River valley channels airflows, while the mid-Atlantic climate produces a well-defined seasonal progression.

How often is the Cherry Hill pollen forecast updated?
The Cherry Hill pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Cherry Hill 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 Cherry Hill 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 Cherry Hill, 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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
