Local Environmental Conditions
A waterway supports hazel and willow along its bank, both strongly allergenic wind-pollinated species; this sits a short distance from here. Here, just around the area, grass and ornamental trees within the park boundary contribute modestly to grass and ragweed levels. The general pattern described here holds fairly steady across nearby areas with similar land cover.
The bank's hazel and willow kick off the pollen season ahead of the rest, peaking in late winter through March. Grass pollen rises through late spring toward a June high point, followed by ragweed's own peak stretch from mid-August into October. Local weather swings can shift these windows slightly, but the overall order tends to hold.

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. |
