Local Environmental Conditions
The riverbank shelters hazel and willow, two trees whose pollen travels readily on the breeze, at a workable 500-600m distance. Nearby, just a short walk at 200-300 meters, oak and birch make up the bulk of this woodland, birch being the more potent allergen of the two. Surrounding neighborhoods with similar tree cover typically see a closely comparable pollen mix.
Hazel and willow along the water get the season underway before other species, usually the first pollen source active, peaking sometime in February or March. As spring advances, oak and birch in the nearby woodland become the dominant source, building to its sharpest point across April and May. Through late spring, grass pollen climbs steadily toward its June peak, before ragweed's late-summer surge carries the season into October.

How often is the Traverse City pollen forecast updated?

Does pollen in Traverse City 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 Traverse City 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 Traverse City, 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. |
