Low today, mostly tree pollen.
Last updated July 28, 2026
Tree pollen is the only category active in Detroit 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 tree pollen may notice mild symptoms, particularly with any outdoor activity. Looking ahead, tree pollen is expected to ease slightly and hold steady at a low level through the next several days. This lines up with the seasonal pattern, since the peak for oak, elm, and other local trees like cladrastis, amelanchier, and honeylocust typically falls in spring rather than midsummer. With that peak well behind us, tree pollen counts should stay calm for the near future.
