Colorado Springs, CO Pollen Levels Today

Colorado Springs sits at roughly 6,000 feet along the Front Range, where a dry, semi-arid climate, intense sunlight, and strong Chinook winds combine to loft pollen across the region and produce a long, pronounced allergy season.

Tree pollen arrives first, typically ramping up in March and peaking through April and May, with juniper and mountain cedar leading the charge alongside cottonwood, elm, ash, oak, maple, and box elder—all widespread throughout the city's parks and foothills neighborhoods.

As trees taper, grass pollen takes over from late May into July, driven largely by Kentucky bluegrass, Timothy, orchard grass, and brome, which are common in lawns, open spaces, and the prairie grasslands east of town.

Weed season then dominates from August through the first hard freeze in October, with ragweed, sagebrush, Russian thistle (tumbleweed), pigweed, and kochia producing the fall's heaviest counts. Overlap between late grasses and early weeds in August can intensify symptoms considerably.

Non-pollen triggers are also significant here: the dry climate kicks up persistent dust, wildfire smoke drifts in during summer, and indoor mold thrives in basements despite low outdoor humidity.

Overall, Colorado Springs is defined by a windy, dust-prone environment with a juniper-heavy spring and a strong ragweed- and sage-driven fall.
