Local Environmental Conditions
Woodland makes up around 47% of the area near Greenwood Village, with a good deal of built-up land and some open grassland. Close to running water, riverside trees such as willow and poplar contribute to what is in the air. Allergenic trees nearby include poplar, elm and oak. Grasses also feature strongly, alongside pigweed and ragweed among the weeds.
First to flower is elm, in early spring. Tree pollen peaks in mid-spring, when the weather warms to around 5°C and poplar and oak are in full flower. Grass pollen follows, peaking in early summer and easing off by early fall. The season closes with pigweed and ragweed from early summer into early fall. Spring is the wettest time of year, and heavy showers can bring short breaks in pollen.

Does pollen in Greenwood Village 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 Greenwood Village 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 Greenwood Village, 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. |
