Local Environmental Conditions
Around 75% of the area near this location in Leadville is woodland. Of the trees nearby, poplar and willow are the ones that matter most for allergies. There is plenty of grass pollen here too. Gaps in the canopy, trails and forest edges give grasses and herbs room to grow.
Tree pollen peaks in late spring, when the weather warms to around 5°C and poplar and willow are in full flower. Then come the grasses, strongest in midsummer and fading by late summer. A smaller weed peak follows from early summer into early fall. By mid-fall, as temperatures fall to around freezing, pollen levels are low again.

How often is the Leadville pollen forecast updated?

Does pollen in Leadville 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 Leadville 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 Leadville, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
