Local Environmental Conditions
Hazel and willow grow along the bank, contributing some of the season's earliest allergenic pollen; this sits just around the area. Nearby, a short distance from here, tree cover made up mostly of oak and birch, both significant spring allergen sources. Here, nearby, this park's mix of turf and landscaped trees contributes a modest grass and ragweed pollen load.
Hazel and willow along the water get the season underway before other species, hitting its peak before most trees have even budded, around late winter into March. Further into spring, the area's oak and birch stands drive the pollen count, peaking in the heart of spring, generally April into May. By late spring, grass pollen is climbing steadily toward a June high point, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

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. |
