Low Pollen in Pittsburgh, PA

About pollen in Pittsburgh

Grass pollen is the main driver in Pittsburgh today, sitting at a Low level (2) and edging out tree pollen, which has dropped to Very Low (1). The forecast holds grass steady at Low for the next several days, while tree counts stay minimal where data is available. That pattern fits the season: the spring surge from trees like Maple, Elm, Linden, Honeylocust, and Pyrus has largely faded, and grasses now take over as the typical late-spring to early-summer source. Overall conditions register as Low (2), so it's a relatively quiet stretch for sensitive individuals. Weed pollen isn't being reported at this time.
