Local Environmental Conditions
This site in Boulder is surrounded mainly by built-up land, with some open grassland and bare ground. Lawns and planted trees in a nearby park add to local grass and tree pollen. Grasses also feature strongly, alongside pigweed among the weeds. Around here, planted trees and mown lawns are the main sources in the built-up parts.
Tree pollen comes first, peaking in early spring. Grasses take over in mid-spring and keep pollen in the air into early fall. Later, pigweed keeps weed pollen in the air from early summer into early fall. In this dry climate, pollen can linger in the air for long spells without rain.

How often is the Boulder pollen forecast updated?

Does pollen in Boulder 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 Boulder 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 Boulder, 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. |
