Local Environmental Conditions
A waterway supports hazel and willow along its bank, both strongly allergenic wind-pollinated species, close by. This area, nearby, has this park's mix of turf and landscaped trees contributes a modest grass and ragweed pollen load. As with most local readings, actual levels can vary somewhat with short-term weather swings.
The waterside hazel and willow are consistently first to release pollen each year, leading off the pollen calendar, with a peak generally falling in late winter. Grass pollen takes over next, building to a peak around June, before ragweed takes over as the dominant allergen from mid-August through October. The overall order of species tends to hold steady, even as exact dates shift slightly each year.

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 West Stockbridge, 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. |
