Local Environmental Conditions
This area, within the neighborhood's edge, has moisture-loving hazel and willow dominate the bank, both quick to release pollen on the wind. Nearby, nearby, oak and birch dominating the treeline, both heavy contributors to the spring pollen load. Nearby weather stations report comparable trends across the broader stretch of the county.
Hazel and willow by the water are typically first out of the gate, leading off the pollen calendar, with a peak generally falling in late winter. Oak and birch in the woods pick up where the earlier species leave off, cresting around April and May in the year's sharpest tree-pollen spike. Through late spring, grass pollen climbs steadily toward its June peak, with ragweed climbing to its own high point from mid-August through October.

Does pollen in Hamiltonban Township come from nearby or far away?

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 Hamiltonban Township 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 Hamiltonban Township, 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. |
