Local Environmental Conditions
For East Bridgewater, here, just outside the immediate area, hazel and willow line the water's edge, releasing pollen that carries easily on the wind. Ground-level conditions like local landscaping can nudge these figures slightly either way. Nearby weather stations report comparable trends across the broader stretch of the county. Small shifts in elevation or soil type can move these figures a little either way.
Around East Bridgewater, hazel and willow by the water are typically first out of the gate, usually peaking sometime between late winter and the end of March. Grass pollen counts rise through late spring, reaching their peak around June, before ragweed's late-summer surge carries the season into 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. |
