Old Colorado City, a neighborhood in Colorado Springs, opens its pollen season with juniper and cottonwood from March with ash following close behind through April. Grass pollen then peaks through May and June, and grass pollen lingers into early September before tapering off. Low humidity and high elevation mean pollen disperses easily once released, which shapes conditions at Old Colorado City much as it does elsewhere in Colorado Springs.

The Colorado Springs pollen forecast is updated four times daily. See the timestamp below for the most recent update.

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.

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 Colorado Springs, 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.
