Red maple
Acer rubrum
Very low today, mostly tree pollen.
Last updated August 15, 2026
Pollen levels around Dearborn are quite mild today, with both tree and weed sources sitting at the low end of the scale. Neither is likely to cause much trouble for most people, even those who tend to be sensitive, and it should be a comfortable day to spend time outside. Looking ahead, expect conditions to stay calm through the week, with a slight uptick in both tree and weed levels midweek before easing again. This time of year, tree pollen from species like oak, maple, and elm is winding down, while weeds such as ragweed are just beginning their seasonal rise as late summer moves toward fall, so a gradual increase in weed pollen wouldn’t be surprising in the coming weeks.
