Colorado Springs' pollen season opens with elm and cottonwood from late February, followed by oak and pine through April and May. Grass pollen peaks through June and July. The elevated Rocky Mountain setting means the season begins later and ends earlier than in lower-altitude US cities, while the surrounding ponderosa pine woodland and open plains contribute substantial tree and grass pollen under variable mountain winds.

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.
