Pollen in Chicago, IL

About pollen in Chicago

Pollen activity in Chicago is minimal today, consistent with mid-November conditions. Trees, grasses, and weeds are all well past their growing and flowering periods, so there is little to nothing circulating in the outdoor air right now. Anyone who normally reacts to pollen should find this a relatively easy stretch. Looking ahead, this quiet pattern should continue through the next several days, as the growing season has wound down across the region. Chicago's tree pollen, from species like oak, maple, and birch, typically does not return until spring, while grass pollen builds in late spring and early summer, and ragweed activity is now also behind us for the year. For the time being, outdoor pollen is unlikely to be a significant concern.
