Local Environmental Conditions
Nearby, within the neighborhood, the waterway's edge supports aspen and willow, species known for wind-carried pollen at elevation. Forest where lodgepole pine and aspen make up much of the canopy, driving spring conifer pollen counts; this sits in the vicinity. A park combining lawn grass and planted trees, both minor but real contributors to pollen here, in the vicinity.
January is the coldest month here at around -4°C, warming to about 21°C by July, and most of the 454 mm annual rainfall falls in the warmer months around July. Expect pollen activity to start building from around February, tracking the rise in temperature out of the January low.

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