About pollen in Roseville

Weed pollen is the main story in Roseville today, sitting at a moderate level that is likely to be noticeable for anyone who reacts to ragweed or similar plants. Grass pollen is running very low and shouldn't cause much trouble, while tree pollen is absent entirely, so those with tree sensitivities should get a break for now. Looking ahead, this pattern is expected to hold steady over the next several days, with weed pollen remaining the primary concern and grass staying at a low, background level. This lines up with the season, as early fall is peak time for weeds like ragweed even as trees such as oak and ash stay dormant until their spring bloom.

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.
