About pollen in Norman

Weed pollen is the main driver of today's very high overall count in Norman, and it is likely to be the most troublesome for anyone sensitive to it. Tree pollen is also running high, while grass sits at a more moderate, noticeable level. Altogether, this adds up to a day when allergy symptoms could be fairly pronounced, particularly for those who react to ragweed and similar late-season weeds. Looking ahead, weed pollen should ease somewhat over the next couple of days before ticking back up slightly toward the end of the five-day stretch, so sensitive individuals may still want to stay mindful outdoors. Tree and grass pollen are both expected to drop off noticeably after today, settling into low territory through midweek before creeping up again. This pattern fits the season well: early fall in Oklahoma is prime time for ragweed and other weeds, while tree pollen from species like oak, elm, and cedar is well past its spring peak and grass pollen is winding down after its late-spring high point.

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.
