Very Low Pollen in Pittsburgh, PA

About pollen in Pittsburgh

Pollen levels in Pittsburgh are quiet today, with both tree and weed pollen sitting at very low levels. Most people should be able to go about their day without much irritation, even those who tend to be sensitive to airborne pollen. There's little to worry about on either front right now. Looking ahead, expect a gradual uptick over the next several days, with tree and weed pollen both edging into the low-to-moderate range by midweek. This time of year, tree pollen from species like honeylocust, elm, pyrus, maple, and zelkova is largely winding down, so the modest rise is more likely tied to weeds as we move deeper into late summer. Sensitive individuals may want to keep an eye on the trend, though conditions overall remain mild for now.
