Last updated November 14, 2026
Pollen is essentially quiet across San Pedro today. Tree pollen, the only category reporting activity this time of year, is sitting at none, which means most people should move through the day without any pollen-related irritation. Looking ahead, conditions are expected to hold steady at this low level over the next several days, so no significant change is on the horizon. This lull fits the season, as local trees like ash, pine, Araucaria, Washingtonia, and pittosporum typically wait until spring to release their pollen in earnest, leaving late fall as a relatively calm stretch for allergy sufferers in the area.
