Silverton sits on a high mountain town at over 9,300 feet in the San Juans, where the dominant vegetation is a mix of Engelmann spruce, alpine wildflower meadows, and willow along the creek, shaping the local pollen profile across the seasons. Exposure varies with proximity to green space versus the more built-up parts of Silverton. The mix of native and introduced species here is fairly typical for this part of the country.

How often is the Silverton pollen forecast updated?

Does pollen in Silverton 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 Silverton 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 Silverton, 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.
