Local Environmental Conditions
The waterway's edge supports aspen and willow, species known for wind-carried pollen at elevation, just outside the immediate area. Woodland dominated by lodgepole pine and quaking aspen, both contributing to the high country's spring pollen, in the wider area. Located close to this spot, this area has maintained parkland where turf grass and ornamental species add to the grass and ragweed mix.
Average temperatures range from about -12°C in January to 18°C in July, and the 546 mm annual rainfall is spread fairly evenly across the year. Pollen activity typically picks up as temperatures climb out of the January low, from around February onward.

Does pollen in Steamboat 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. 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 Steamboat 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 Steamboat 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. |
