Local Environmental Conditions
Nearby, in the wider area, aspen and willow line the water's edge here, releasing pollen that carries on the thin mountain air. Here, in the vicinity, grass and ornamental trees within the park boundary contribute modestly to grass and ragweed levels. Year-to-year swings in rainfall and wind can shift this picture somewhat either way.
Temperatures here typically swing from about -10°C in January up to 18°C in July; the 566 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.

When is pollen season in Eagle?
How often is the Eagle pollen forecast updated?
The Eagle pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Eagle 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 Eagle 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 Eagle, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
