Moderate Pollen in Boston, MA

About pollen in Boston

Tree pollen is the main driver in Boston today, sitting at the High end of the index and pushing the overall reading to High as well. Local species such as oak, maple, elm, honeylocust, and amelanchier are behind this elevated count. The forecast points to sharp relief on that front, with tree levels dropping to low and holding there over the next five days. Grass pollen is currently Moderate and is expected to stay steady at that level through the period, which is typical for late spring into early summer as grasses become the more persistent source. With the calendar turning toward summer, the spring tree peak is winding down while grass settles into its seasonal stride. Weed pollen data is unavailable today.
