About pollen in Columbia

Weed pollen is the main driver of today's conditions in Columbia, and it's running high enough to bother those who are sensitive to it. Tree pollen is barely present, and grass is only a minor factor at this point, so most of the irritation people feel outdoors today will likely trace back to weeds. Expect weed pollen to ease noticeably tomorrow before climbing again through the rest of the week, so sensitive individuals should prepare for another uptick rather than assuming the dip will hold. Grass and tree pollen should stay low and largely unremarkable over the next several days. This pattern fits the season well: with oaks, pines, and other regional trees long past their spring release and grasses winding down, early fall in the Midlands is ragweed's time to shine, and it will likely remain the pollen type to watch into the coming weeks.

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).
