Local Environmental Conditions
Nearby, in the vicinity, a stretch of hazel and willow lines the water, feeding some of spring's earliest pollen. Located within the neighborhood, this area has a wooded stretch of oak and birch, with birch responsible for some of the sharpest spring counts. This area, nearby, has green space with maintained lawn and planted trees, both contributing to grass and ragweed counts.
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. By mid-spring, oak and birch in the woods take over, generally peaking somewhere between April and May. By late spring, grass pollen is climbing steadily toward a June high point, with ragweed climbing to its own high point from mid-August through October.

Does pollen in Natick 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 Natick 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 Natick, 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. |
