Low Pollen in Madison, WI

About pollen in Madison

Tree pollen is the only category showing activity in Madison today, and it remains at a low level. Most people should get through the day without much irritation, though those who are especially sensitive to species like ash, maple, or hackberry (Celtis) may notice a mild effect during extended time outdoors. Looking ahead, tree pollen is expected to ease slightly and hold steady at a low level through the next several days, meaning conditions should stay comfortable for most of the week. This fits the seasonal pattern, as tree pollen typically peaks in spring and tapers off by midsummer, with trees like Syringa and Corylus largely finished releasing pollen by this point in the year.
