Local Environmental Conditions
Around Pocasset Golf Club, hazel and willow grow along the bank, contributing some of the season's earliest allergenic pollen, nearby. Located nearby, this area has a wooded stretch of oak and birch, with birch responsible for some of the sharpest spring counts. Grass and ornamental trees within the park boundary contribute modestly to grass and ragweed levels; this sits within the neighborhood.
At Pocasset Golf Club, hazel and willow near the water open the pollen calendar early, hitting its peak before most trees have even budded, around late winter into March. Late spring sees grass pollen build steadily toward a peak in June, then yields to ragweed, the dominant late-summer and fall allergen through October.

Does pollen in Bourne come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Bourne based on measurements or forecasts?
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 Bourne, 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. |
