Moderate today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in Dearborn today, sitting at moderate levels and accounting for the overall moderate reading. Tree pollen has dropped to very low, with the local oak, maple, zelkova, celtis, and elm now well past their springtime peak. The forecast keeps grass steady at moderate for the next few days before easing slightly toward the end of the window, while tree counts hold flat at very low throughout. This pattern is typical for late June, when grass pollen tends to dominate as the tree season winds down. Weed pollen is not being reported at this time, so ragweed isn't a factor yet—that tends to arrive later in summer and into fall.
