Cambridge is enjoying a quiet stretch on the pollen front today, with tree pollen sitting at essentially none. For anyone sensitive to airborne allergens, this should be a comfortable day with little to no irritation expected from trees around the city. Looking ahead, tree pollen is expected to tick up slightly over the next few days, moving from none to a low level. This modest uptick is not unusual for midsummer, since the major tree pollen season from oaks and similar species has long passed. Any pollen from trees like Ginkgo, Hamamelis, or Larix at this point would be minor background activity rather than a significant seasonal push. Overall, conditions remain mild, and there is little cause for concern in the near term.
