About pollen in Topeka

Weed pollen is the main story in Topeka today, running high and likely to cause noticeable symptoms for those who are sensitive to it. Grass pollen, by contrast, is barely registering and shouldn't cause much trouble. This pattern is typical for late September, when ragweed and other late-season weeds dominate the pollen picture. Looking ahead, weed pollen is expected to stay high for the next couple of days before easing to a more moderate level, so anyone affected should plan for continued discomfort into early next week. Grass pollen should remain minimal throughout this stretch. Tree pollen isn't a concern this time of year, since oaks, maples, and other regional trees typically release their pollen in spring rather than fall. Overall, ragweed remains the pollen type to watch as the season winds down.

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).
