About pollen in Kansas City

Weed pollen is the main concern in Kansas City today, running high and likely noticeable for anyone sensitive to it. Grass pollen remains low in comparison, contributing little to overall discomfort. Combined, conditions lean toward the more irritating end of the scale, largely driven by weeds this time of year. Looking ahead, weed pollen is expected to stay high for the next couple of days before easing off toward the middle of the week, then ticking back up slightly afterward. Grass pollen should continue to fade, dropping to low levels as the season winds down. This pattern fits typical fall conditions in the region, when ragweed and related weeds are the dominant source of pollen, 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).
