About pollen in Overland Park

Weed pollen is dominating the air in Overland Park today, reaching levels that are likely to cause significant discomfort for anyone with sensitivities. This is the main driver of overall pollen activity right now, while grass remains low and trees are quiet for the season. Expect weed pollen to stay very high for another day before easing considerably, then climbing back into the moderate range as the week progresses. This pattern is typical for early fall, when ragweed and related weeds are at their most active. Grass pollen should continue to fade into the background over the coming days, and with trees like maple, pine, ash, oak, and pyrus well past their spring release, tree pollen is not a concern at this time of 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).
  • Make sure to use an air purifier with HEPA filter in your home, especially in your bedroom. Don't forget to perform regular filter maintenance checks.
