Local Environmental Conditions
As one of the world's largest hot-spring-fed swimming pools, Glenwood Hot Springs Pool draws on the same plant life found across Glenwood Springs, keeping its pollen sources in step with the wider area. As with most sublevel sites, local landscaping can shift counts slightly from the citywide average.
Glenwood Hot Springs Pool tracks Glenwood Springs's broader pollen pattern, with juniper and cottonwood appearing from March with ash taking the lead through April. A grass pollen peak follows through May and June; grass pollen lingers into early September before tapering off. Low humidity and high elevation mean pollen disperses easily once released, consistent with the wider Glenwood Springs area.

Does pollen in Glenwood Springs 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.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Glenwood Springs 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 Glenwood Springs, 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. |
