Local Environmental Conditions
Here, just outside the immediate area, hazel and willow cluster near the water, an early and reliable source of allergenic pollen. This area, nearby, has woods composed largely of oak and birch, a combination tied to sharp spring pollen spikes. This area, a short distance from here, has mown grass and ornamental trees in a nearby park, adding to seasonal grass and ragweed pollen.
The waterside hazel and willow are consistently first to release pollen each year, arriving ahead of the rest of the season, cresting around late winter. Once hazel fades, oak and birch in the woods carry the season forward, cresting around April and May in the year's sharpest tree-pollen spike. Grass pollen counts rise through late spring, reaching their peak around June, and ragweed later takes the lead from mid-August through October.

How often is the Menominee pollen forecast updated?
The Menominee pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Menominee 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 Menominee 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 Menominee, 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. |
