About pollen in Kansas City

Weed pollen is the main driver of today's high overall count in Kansas City, with ragweed likely behind much of the activity this time of year. Anyone sensitive to weed pollen should expect noticeable symptoms today. Grass pollen, by contrast, is low and shouldn't cause much trouble. Looking ahead, weed pollen is expected to stay high for the next couple of days before easing off toward the middle of the week, offering some relief for those affected. Grass pollen should continue its gradual decline as the season winds down. This pattern fits typical late-September conditions in the region, when ragweed dominates the pollen picture while tree pollen from species like oak and maple remains dormant until spring.

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).
