About pollen in Memphis

Weed pollen is the main driver of today's conditions in Memphis, running high and likely to be noticeable for anyone with sensitivities. Tree and grass pollen are both light by comparison, so most of the irritation in the air right now can be traced back to weeds, particularly ragweed, which tends to dominate the fall allergy picture in this region. Looking ahead, weed pollen is expected to ease slightly over the next couple of days before climbing back into the high range by the end of the stretch, so sensitive individuals should expect conditions to remain persistent rather than fading quickly. Tree and grass pollen should stay low and fairly steady throughout the period. This pattern fits the season well, as oak, elm, and other area trees are long past their spring peak and grasses have wound down, leaving ragweed as the dominant source of fall allergy symptoms across the Mid-South.

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).
