Pollen in Cambridge, MA

About pollen in Cambridge

Pollen is essentially quiet around Cambridge today, with tree pollen sitting at none. Anyone sensitive to allergens should get an easy day, with little to no irritation expected from the air outside. Looking ahead, the forecast shows tree pollen staying flat near zero over the next stretch, which lines up with the season. Mid-November falls well outside the active window for trees like oak, ginkgo, witch hazel (hamamelis), sweetgum (liquidambar), and larch, all of which typically release their pollen in spring rather than late fall. Expect this calm stretch to continue for now, with the next real uptick in tree pollen not arriving until spring growth resumes.
