Pollen in Centennial, CO

About pollen in Centennial

Pollen counts in Centennial are quiet today, with tree pollen sitting at essentially none. For anyone sensitive to airborne allergens, this should be an easy day with little to no irritation expected from trees or other sources. Looking ahead, conditions are expected to remain calm over the next several days, with tree pollen staying at a non-factor level. This lines up with the season: mid-November falls well outside the active growing period for trees like ash, linden, pyrus, spruce, and pine in this region, all of which typically release their pollen in spring. With those trees dormant for the winter, there is little reason to expect any meaningful pollen activity in the near term.
