About pollen in Warren

Grass pollen is the main driver in Warren today, sitting at a moderate level (3) and accounting for most of the overall moderate reading. Tree pollen has dropped off to very low (1), with the area's maple, elm, Celtis, oak, and Amelanchier well past their spring peak. The forecast holds grass steady at moderate for the next several days before easing slightly toward the end of the window, so expect little change in the near term. This pattern fits the season, as grasses typically dominate through late spring and early summer while tree activity winds down. Weed pollen is not reported in today's data.

What to do today

  • It's important to shower and wash your hair after spending a lot of time outdoors.
  • When spending time outside, use sunglasses and a cap to keep pollen out of your face and eyes.
  • Wash clothes worn outdoors to remove any remnants of pollen grains.
  • If possible, wear glasses instead of contact lenses.
  • Did you hang any laundry outside? Now is a good time to hang clothes indoors or use a dryer if possible.
