Local Environmental Conditions
Nearby, a comfortable 200-300 meters away, hazel and willow grow along the bank, contributing some of the season's earliest allergenic pollen. Nearby, about 300-400 meters off, this patch of forest is largely oak and birch, a pairing known for heavy spring pollen output. This area, right at hand, some 100-200m away, has a park whose turf grass and ornamental plantings feed local grass and ragweed pollen levels.
Near the bank, hazel and willow lead the seasonal calendar, 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, building to its sharpest point across April and May. Through late spring, grass pollen climbs steadily toward its June peak, with ragweed then rising to the fore from mid-August through 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. |
