About pollen in Fort Collins
Pollen activity in Fort Collins is minimal today, consistent with mid-November conditions. With trees dormant and grasses and weeds past their growing season, there is little plant pollen circulating in the air right now, so most allergy sufferers should find this a comfortable stretch. Looking ahead, this quiet pattern is likely to continue through the next few days, as cooler temperatures and the late-autumn season keep plants inactive. Fort Collins will not see meaningful pollen again until late winter or early spring, when trees such as juniper, elm, and cottonwood typically begin to release pollen. Grass follows in late spring to early summer, and ragweed becomes the main concern in late summer into fall, so for now the season offers a natural break for anyone sensitive to airborne pollen.
