Local Environmental Conditions
The riverbank shelters hazel and willow, two trees whose pollen travels readily on the breeze; this sits within the local area. Oak and birch dominating the treeline, both heavy contributors to the spring pollen load; this sits a short distance from here. This area, in the vicinity, has mown grass and ornamental trees in a nearby park, adding to seasonal grass and ragweed pollen.
Near the bank, hazel and willow lead the seasonal calendar, 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, reaching maximum intensity across the April-May window. Grass pollen climbs toward a June peak, with ragweed climbing to its own high point from mid-August through October.

Does pollen in Coon Rapids 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 Coon Rapids 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 Coon Rapids, 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. |
