About pollen in Santa Monica

Weed pollen is the main presence in Santa Monica today, though it remains at a low level that most people won't notice. Grass is nearly absent, registering only a trace, and tree pollen is quiet with no activity to speak of. Overall, this adds up to an easy day for allergy sufferers, with little reason for concern. Looking ahead, this pattern should hold steady through the next several days. Weed pollen may tick up slightly at times but is expected to stay in the low range, while grass continues to linger at a very low level. Tree pollen should remain absent, which fits the season, since local trees like Prunus, Washingtonia, Eucalyptus, Plane, and Pine typically release their pollen in spring rather than fall. The late-season weed presence, on the other hand, is typical for this time of year as autumn weed pollen makes its final appearances before tapering off.
