Platanus acerifolia
Moderate today, mostly tree pollen.
Last updated September 30, 2026
Tree pollen is the more active category in Elmhurst today, sitting at a moderate level that may be noticeable if you're sensitive, particularly with ash, plane, maple, oak, and birch trees still contributing this time of year. Weed pollen is present but low, so it shouldn't be much of a factor for most people right now. Looking ahead, weed pollen is expected to stay low over the next several days, with only slight day-to-day shifts and no significant rise in sight. This lines up with the season, as tree pollen is well past its spring peak and weed pollen, including ragweed, typically continues to ease as autumn moves along. Overall, conditions look manageable through the week, with tree pollen worth keeping an eye on if you tend to react to it.
