Platanus acerifolia
Moderate today, mostly tree pollen.
Last updated August 15, 2026
Tree pollen is the most active type in Elmhurst today, sitting at a moderate level that could be noticeable for those who are sensitive, particularly to species like ash, plane, maple, oak, and birch. Weed pollen is present as well, but at a lower level that should be easy for most people to manage. Looking ahead, tree pollen is expected to ease significantly over the next several days, dropping to a low level and staying there through the period. Weed pollen will also settle into a generally low range, with a slight uptick midweek before easing again. This pattern fits the season, as mid-August tree pollen tends to be a lingering presence rather than a major factor, while weed pollen, including ragweed, is just beginning its climb toward the more active stretch typical of late summer and early fall.
