Very low today, mostly tree pollen.
Last updated August 15, 2026
Pollen levels around Cambridge are quiet today, with both tree and weed sources registering very low. Neither should cause much trouble for most people, and even those with sensitivities are unlikely to notice much of an effect. Looking ahead, conditions are expected to hold steady over the next several days, with tree pollen staying minimal and weed pollen inching up slightly by the end of the stretch. This lull fits the season: the trees common to the area, including oak, ginkgo, and witch hazel, released their pollen earlier in the year and are largely finished for now, while weeds such as ragweed typically build toward their peak later in the season. For the moment, air quality on the pollen front remains calm and manageable.
