About pollen in Clarksville

Weed pollen is the main concern in Clarksville today, running high and likely to cause noticeable symptoms for anyone sensitive to ragweed. Tree and grass pollen are both quiet, so any discomfort you notice is almost certainly weed-related rather than coming from those sources. Looking ahead, weed pollen is expected to stay high for the next couple of days before easing slightly, though it will remain a factor into the following days. This lines up with the season, as ragweed typically dominates through late summer and into fall in this region. Tree pollen, which usually comes from local species like oak, maple, and hickory, remains far past its spring peak and should stay low, with grass pollen similarly minimal at this point in the year.

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).
