Ridgway sits on a mountain valley beneath the Sneffels Range, where the dominant vegetation is a mix of cottonwood along the Uncompahgre River, sagebrush, and aspen groves nearby, shaping the local pollen profile across the seasons. Exposure varies with proximity to green space versus the more built-up parts of Ridgway. Residents who spend time outdoors around Ridgway typically notice the shift as each season turns over.

How often is the Ridgway pollen forecast updated?

Does pollen in Ridgway 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 Ridgway 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 Ridgway, 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.
