Local Environmental Conditions
Staten Island's parks, including Snug Harbor and the Staten Island Greenbelt, feature oak, maple, and birch as the main tree pollen sources, with exposure varying between these green areas and the more densely built parts of the borough. The Kill Van Kull and Arthur Kill waterways mean coastal breezes can periodically disperse pollen, while surrounding New Jersey woodland and farmland contribute additional tree and grass pollen.
Staten Island's pollen season opens with maple and birch from late February, followed by oak through April and May. Grass pollen peaks through June and July, with ragweed extending the season into September. As part of the New York metropolitan area the season is well-defined and intense, while the Kill Van Kull and Arthur Kill waterways mean coastal breezes can occasionally moderate pollen levels along the shoreline.

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