About pollen in Fort Collins
Pollen levels in Fort Collins are quiet today, with weeds the only category showing any activity, and even that is very low. Most people should notice little to nothing outdoors, including those who tend to be sensitive to ragweed and other late-season weeds. Looking ahead, conditions are expected to hold steady over the next couple of days, with weed pollen staying at a similarly low level. This fits the seasonal pattern, as early fall is when ragweed and related weeds are winding down after their late-summer peak, while tree pollen from cottonwoods, elms, and junipers remains dormant until it returns in spring. Overall, this is a comfortable stretch for anyone who deals with seasonal allergies.
