Local Environmental Conditions
Ridgewood Park — Here, some 315 meters out, hazel and willow line the water's edge, releasing pollen that carries easily on the wind. Parkland with regularly mown grass and planted trees, both sources of grass and ragweed pollen; this sits a stone's throw away, around 151m. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall.
The bank's hazel and willow kick off the pollen season ahead of the rest, hitting its peak before most trees have even budded, around late winter into March. Grass pollen climbs toward a June peak, with ragweed then rising to the fore from mid-August through October. Daily pollen counts published for the wider region track this same seasonal rhythm closely.

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. |
