About pollen in Alhambra

Weed pollen is the main story in Alhambra today, sitting at a moderate level that sensitive individuals will likely notice. Tree pollen is quiet, and grass remains at a very low level, so most of the day's allergy discomfort, if any, will trace back to weeds rather than trees or grasses. Looking ahead, weed pollen is expected to ease slightly over the next several days but stay in a range that could still bother those who react to it, while grass holds steady at its current low level and tree pollen remains absent. This pattern fits the season well: local trees such as plane, mulberry, crape myrtle, ficus, and Mexican fan palm have already finished their spring release and are not contributing right now, while weeds typically remain the dominant allergen through late summer and into fall.

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.
