About pollen in Waco

Pollen is running high in Waco today, with both tree and weed sources active enough to cause noticeable symptoms for anyone with sensitivities. Grass is contributing as well at a moderate level, so those prone to reactions from multiple sources may feel the combined effect more than usual. Overall, today calls for a bit more caution than a typical late-September day. Looking ahead, tree and weed pollen are expected to stay high through tomorrow before dropping sharply, with a quiet, low-pollen day likely by midweek. After that, levels should tick back up gradually toward the end of the forecast period, though staying more moderate than today's readings. This pattern fits the season well: true tree pollen usually peaks in spring, but some regional trees can still release small amounts into fall, while ragweed and other late-season weeds are the main drivers of the current high weed counts, a typical feature of early autumn in Central Texas.

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).
