Local Environmental Conditions
For Harmon Golf and Fitness Club, the waterside growth here is largely hazel and willow, both efficient wind-pollen dispersers; this sits just around the area. Located in the vicinity, this area has woods composed largely of oak and birch, a combination tied to sharp spring pollen spikes. The general pattern described here holds fairly steady across nearby areas with similar land cover.
For Harmon Golf and Fitness Club, oak and birch in the nearby woodland follow in mid-to-late spring, peaking in the heart of spring, generally April into May. Hazel and willow along the water get the season underway before other species, building through the tail end of winter into March. Through late spring, grass pollen climbs steadily toward its June peak, and ragweed later takes the lead from mid-August through October.

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