Pollen in Philadelphia, PA

About pollen in Philadelphia

Conditions in Philadelphia are calm on the pollen front today. Late July typically falls in a quiet stretch between the spring and early-summer plant cycles, so most people should find the air fairly easy to tolerate, even those who usually react to airborne allergens. Looking ahead, this lull is likely to continue for now. Area trees such as oak, maple, and birch finished releasing pollen back in spring, and grass activity usually tapers off by midsummer, so neither should cause much trouble in the coming days. The next shift to watch for is ragweed, which tends to become the dominant allergen starting in late summer and running into fall, so it's worth keeping an eye on conditions as August approaches.
