Fraxinus pennsylvanica
Very high today, mostly weed pollen.
Last updated August 15, 2026
Weed pollen is dominating the air in Colorado Springs today, reaching a very high level that is likely to affect even those with mild sensitivities. Tree pollen is quiet, so if you are feeling stuffy or itchy-eyed, weeds are almost certainly the cause. Looking ahead, weed pollen will remain the main concern through the next several days, staying high with only a slight dip expected before climbing again. This tracks with the season, as late summer is peak time for ragweed and other weeds to release pollen, while trees like ash, oak, and elm have long since finished their spring runs and won't be a factor again until next year.
