Local Environmental Conditions
The center of Colo Heights is heavily wooded. A stream or river nearby means riverside vegetation is part of the local pollen picture. Woodland on all sides makes trees an important local pollen source. Grass pollen is a substantial part of the local mix as well. Undergrowth, clearings and woodland edges add smaller amounts of grass and herb pollen.
Tree pollen comes first, peaking in late winter. Grasses take over in mid-spring, with temperatures around 15°C, and their pollen lingers into late summer. Weeds on open ground add a smaller late peak from early summer into early fall. Fall is the wettest time of year, and heavy showers can bring short breaks in pollen.

Does pollen in Colo Heights 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 Colo Heights 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 Colo Heights, 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. |
