Local Environmental Conditions
Open grassland makes up around 32% of the area near the heart of Silverton, with some woodland and bare ground. With a stream or river close by, riverside trees such as willow contribute to the local mix. Allergenic trees nearby include willow. Grasses add a sizeable share of the local pollen.
Willow leads the season in late spring, as temperatures climb to around 5°C, and tree pollen reaches its peak. Then come the grasses, strongest in midsummer and fading by late summer. Weeds on open ground add a smaller late peak from early summer into early fall. By mid-fall, as temperatures fall to around 5°C, pollen levels are low again.

How often is the Silverton, Colorado pollen forecast updated?

Does pollen in Silverton, Colorado 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, Colorado 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, Colorado, 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.
