Pollen is essentially a non-issue in Santa Rosa today. Tree pollen is sitting at none, and with no grass or weed readings being reported, there is nothing circulating that should bother even those with sensitive sinuses. It is a good day to be outdoors without much concern about airborne allergens. Looking ahead, conditions are expected to stay quiet, with tree pollen holding at none through the available forecast. This fits the season: mid-November falls well after the fall weed pollen has wound down and long before local trees like willow, flowering pear, oak, hackberry, and redwood begin releasing pollen in late winter and spring. Barring any unusual weather shifts, allergy sufferers in the area should get a comfortable stretch before activity picks up again.
