Local Environmental Conditions
This area, practically next door, 50 meters off, has the waterway's edge supports hazel and willow, species known for potent, wind-carried pollen. This area, a comfortable 300-400 meters away, has a stand of oak and birch, the latter ranked among the region's most potent tree allergens. Small shifts in elevation or soil type can move these figures a little either way.
Water-edge hazel and willow are usually the first allergenic trees active here, hitting its peak before most trees have even budded, around late winter into March. Oak and birch in the woods pick up where the earlier species leave off, typically the year's sharpest tree-pollen spell, centered on April and May. Late spring brings rising grass pollen that crests in June, followed by ragweed's own peak stretch from mid-August into October.

How often is the Sebewaing pollen forecast updated?

Does pollen in Sebewaing 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 Sebewaing 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 Sebewaing, 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. |
