Low today, mostly weed pollen.
Last updated August 14, 2026
Weed pollen is the more noticeable presence in Detroit today, though it remains at a low level overall. Tree pollen is quiet, with trees like oak, maple, and elm largely finished shedding for the season. Most people should get through the day without much irritation, though those especially sensitive to weed pollen may notice a mild effect. Looking ahead, this pattern is expected to hold steady over the next several days, with tree pollen staying very low and weed pollen continuing at a low level with only slight day-to-day variation. This lines up with what's typical for mid-August, as tree pollen season is long over and ragweed and other late-summer weeds gradually become the main source of pollen heading into fall. Overall, conditions look manageable for the week ahead.
