Local Environmental Conditions
Jackson's south-central Michigan setting features oak, maple, and birch as the main tree pollen sources, with exposure varying between the wooded Cascade Falls and Falling Waters Trail corridor areas and the more built-up commercial areas along Michigan Avenue. The Grand River corridor provides locally significant green space, while the surrounding Jackson County farmland extends substantial grass pollen and the flat landscape allows wide dispersal during summer throughout the season.
Jackson's pollen season in Wyoming opens with cottonwood and sage from late March, later than lower-altitude US cities due to the high mountain valley setting at nearly 6,500 feet. Pine and grass follow through May and June. The Jackson Hole valley and surrounding Teton and Gros Ventre Mountain ranges channel airflows and concentrate pollen, while the short mountain summer means the season is compressed but can be intense during the brief peak period.

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