About pollen in Green Bay
Grass pollen is the main driver in Green Bay today, sitting at a Low level (2) and accounting for the overall Low reading. Tree pollen has dropped off to Very Low (1), which fits the late-June timing now that the spring surge from regional trees like oak, birch, and maple has faded. Looking ahead, grass should hold steady around Low through most of the five-day window, easing slightly midway before nudging back up. Tree pollen is forecast to stay flat at Very Low throughout. This is the stretch when grass typically dominates, so expect those levels to remain the more noticeable factor for now. Weed pollen data isn't available, though ragweed generally doesn't ramp up until later in the summer.
