Low Pollen in Warren, MI

About pollen in Warren

Pollen levels in Warren are low today, with weeds edging out trees as the main source in the air. Tree pollen is nearly nonexistent at this point in the season, so trees like maple, elm, celtis, oak, and amelanchier aren't contributing much right now. Weed pollen is present but mild, and most people should get through the day without much irritation, even those who tend to be sensitive. Looking ahead, tree pollen should stay minimal through the next several days, which is typical for mid-August since these species released their pollen back in spring. Weed pollen is expected to fluctuate a bit, ticking up to a more noticeable level midweek before easing again. This pattern lines up with the season, as late summer marks the start of ragweed and other weed pollens becoming more active, a trend that will likely continue into fall.
