About pollen in Lexington
Weed pollen is the dominant force in Lexington today, running high enough that sensitive individuals will likely notice symptoms if spending extended time outdoors. Grass pollen, by contrast, is barely present and shouldn't cause much trouble. For anyone affected by ragweed, this is the kind of day to be mindful of outdoor plans, especially in the afternoon when pollen tends to circulate most. Looking ahead, weed pollen is expected to hold steady at a high level for the next several days before dropping off sharply toward the end of the stretch. Grass will remain a minor factor throughout, staying low. This pattern fits the season well: late September is peak time for ragweed and other weedy plants across the Bluegrass region, while the oaks, maples, and other trees that dominate spring allergy season are dormant and not a concern right now.
