About pollen in Fort Collins
Late July tends to be a quieter stretch for pollen in Fort Collins, and today looks consistent with that seasonal lull. Tree pollen from species like cottonwood, ash, and elm wrapped up months ago, and while grasses can still release some pollen into early summer, activity typically tapers off by this point in the season. Ragweed and other late-season weeds haven't yet kicked into gear, so most allergy sufferers should find today fairly manageable. Looking ahead, expect conditions to remain calm for the next few days, with grass pollen continuing its gradual decline as summer progresses. The bigger shift to watch for is the arrival of ragweed season, which typically begins to build in the region as late summer approaches. For now, this remains a relatively easy time of year for those sensitive to airborne pollen, with the next notable change likely still weeks away.
