Cortez's setting on a high-desert valley town near Mesa Verde in southwestern Colorado supports sagebrush steppe, piñon-juniper woodland, and irrigated hayfields as the leading local vegetation, all factoring into the pollen count through the year. Counts here rise and fall with the same broad rhythm as other places sharing this setting. Microclimates within the area can shift the timing slightly from one neighborhood to the next.

How often is the Cortez pollen forecast updated?
The Cortez pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Cortez 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 Cortez 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 Cortez, 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.
