Gunnison sits on a high mountain valley town in west-central Colorado, where the dominant vegetation is a mix of sagebrush steppe, aspen and spruce forest on the surrounding hills, and riverside willow, shaping the local pollen profile across the seasons. Local parks and open ground tend to see higher pollen counts than the denser urban core. Residents who spend time outdoors around Gunnison typically notice the shift as each season turns over.

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 Gunnison 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 Gunnison, 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.
