Local Environmental Conditions
This area, not far from here, has hazel and willow line the water's edge, releasing pollen that carries easily on the wind. A park whose turf grass and ornamental plantings feed local grass and ragweed pollen levels, not far from here. The broader area tends to mirror this pattern, with only minor local variation.
The water-adjacent hazel and willow are early risers, hitting its peak before most trees have even budded, around late winter into March. Moving into early summer, grass pollen climbs to its seasonal high in June, before ragweed becomes the more dominant allergen from mid-August into October. Local weather swings can shift these windows slightly, but the overall order tends to hold.

Does pollen in Wayland 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 Wayland 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 Wayland, 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. |
