Local Environmental Conditions
Around Adrian, here, within the neighborhood, hazel and willow thrive along the damp bank, both prolific early wind-pollinators. A nearby park's turf and ornamental trees layer grass and ragweed pollen onto the seasonal mix, just outside the immediate area. Small shifts in elevation or soil type can move these figures a little either way.
For Adrian, along the waterway, hazel and willow release pollen first, climbing steadily from late winter into March. Late spring sees grass pollen build steadily toward a peak in June, with ragweed then rising to the fore from mid-August through October. Local weather swings can shift these windows slightly, but the overall order tends to hold.

Does pollen in Adrian 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 Adrian 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 Adrian, 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. |
