Local Environmental Conditions
This area, close to this spot, has the water's edge is thick with hazel and willow, whose pollen spreads readily in early spring. Nearby, just around the area, well-kept lawns and ornamental trees in this park add their share of grass and ragweed pollen. Local wind exposure and land use can shift the exact mix slightly from block to block.
The water-adjacent hazel and willow are early risers, climbing steadily from late winter into March. Grass pollen becomes the dominant allergen through late spring, peaking in June, followed by ragweed's own peak stretch from mid-August into October. Regional pollen monitoring generally reflects this same pattern across nearby areas. Small variations in local weather can nudge these windows a few days in either direction.

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. |
