About pollen in Glendale

Weed pollen is the main story in Glendale today, sitting at a moderate level that could be noticeable if you're prone to allergies. Grass is present but only at a very low level, and tree pollen is quiet with essentially nothing in the air right now. Looking ahead, weed pollen is expected to ease slightly over the next several days but should remain at a moderate level worth keeping in mind, while grass stays steady at its current low level. Tree pollen should continue to be absent, which fits the season — trees like magnolia, eucalyptus, acacia, Washingtonia palm, and liquidambar typically release their pollen in spring, not now. This time of year, in late September, weeds are the more common source of irritation as they move through their late-season peak.

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.
