Local Environmental Conditions
At East Dennison Camping Area, nearby, a short distance from here, hazel and willow line the water's edge, releasing pollen that carries easily on the wind. Located near this part of town, this area has woods composed largely of oak and birch, a combination tied to sharp spring pollen spikes.
At East Dennison Camping Area, oak and birch in the nearby woodland follow in mid-to-late spring, reaching its high point through April and into May. Grass pollen takes over next, building to a peak around June, and then ragweed picks up the slack, running from mid-August through October. Local weather swings can shift these windows slightly, but the overall order tends to hold.

How often is the Winchendon pollen forecast updated?

Does pollen in Winchendon 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 Winchendon 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 Winchendon, 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. |
