Local Environmental Conditions
The vegetation around Meeker, on a mountain-valley ranching town in northwestern Colorado, is dominated by sagebrush steppe and aspen forest on the surrounding hills, with riverside cottonwood adding further seasonal pollen exposure. This mix of plant life is fairly typical for the wider area around Meeker. Nearby towns with similar terrain tend to see a broadly similar pattern.
Meeker's tree pollen season begins with juniper and cottonwood from March with ash taking the lead through April. Grass pollen builds through May and June, and grass and sagebrush extend exposure into September. The semi-arid high-elevation climate means fewer rainfall interruptions than in wetter US regions, shaping conditions across the city.

When is pollen season in Meeker?
How often is the Meeker pollen forecast updated?
The Meeker pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Meeker 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 Meeker 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 Meeker, 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 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. |
