Platanus acerifolia
Moderate today, mostly tree pollen.
Last updated October 14, 2026
Tree pollen is the main contributor to today's moderate conditions in Elmhurst, with ash, plane, maple, oak, and birch trees still releasing some pollen into the air. Sensitive individuals may notice mild to moderate symptoms, though most people should find the day manageable. Weed pollen remains very low and is unlikely to cause much trouble. Looking ahead, tree pollen should hold steady at a similar moderate level, while weed pollen stays consistently low through the next several days. This pattern is a bit unusual for mid-October, when tree pollen is typically winding down for the year — a stretch of mild or unseasonably warm weather can sometimes keep certain trees active later than usual. As autumn progresses, overall pollen levels should continue to ease, with weed pollen fading further as the season moves toward winter dormancy.
