Fraxinus velutina
Low today, mostly grass pollen.
Last updated September 29, 2026
Grass and weed pollen are both running low in Spring Valley today, while tree pollen is quiet. Most people won't notice much of an effect, though those who are especially sensitive to grass or weed pollen may feel a mild trace of irritation. Overall, it's an easy day to be outdoors. Looking ahead, this pattern should hold steady through the next several days, with grass and weed levels staying low and tree pollen remaining absent. This lines up with the season — local trees such as Celtis, Ash, Eucalyptus, Oak, and Rhus are well past their spring release, and while weeds like ragweed can still linger into early fall, current levels suggest a calm stretch for allergy sufferers in the near term.
