About pollen in Clarksville

Weed pollen is the main driver of today's conditions in Clarksville, with levels running high enough to cause noticeable symptoms for those who are sensitive. Tree and grass pollen are both quiet right now, so any irritation you feel is almost certainly coming from ragweed and similar late-season weeds rather than trees or grasses. Looking ahead, weed pollen should stay high tomorrow before easing up significantly, dropping to minimal levels by midweek and then climbing back into the moderate range for the following couple of days. Tree and grass pollen are expected to remain low throughout this stretch, which fits the season — oak, maple, and other local trees won't become active again until spring, and grasses typically wait until late spring or early summer. For now, ragweed remains the pollen type to keep in mind as autumn continues.

What to do today

  • Avoid mowing the lawn and raking leaves.
  • When driving the car, close your windows and turn the air conditioning system to recirculation mode.
  • Keep your windows closed and turn on your air purifier or air conditioning.
  • Consider staying indoors during the peak pollen hours (morning and early afternoon).
