No notable pollen right now.
Last updated November 14, 2026
Stockton's air is clear of pollen today, with tree sources quiet and no notable activity to report. Those who usually feel the effects of tulip trees, pistache, crape myrtle, privet, or sweetgum should get a welcome break, as conditions are calm across the board. Looking ahead, this lull is expected to hold over the next several days, which fits the season well. Mid-November falls outside the active windows for local trees, which typically release pollen in spring, so little change is anticipated in the near term. This is a good stretch for anyone sensitive to tree pollen to enjoy some relief before growth resumes later in the year.
