About pollen in Philadelphia
Weed pollen is the only type active in Philadelphia today, and it remains at a low level. Most people should move through the day without any issues, though those who are especially sensitive to ragweed and similar late-season weeds may notice mild effects, particularly outdoors in the afternoon. Looking ahead, weed pollen is expected to hold steady at a low level over the next couple of days before easing slightly further by midweek. This fits the season well, as October marks the tail end of ragweed's run before cooler weather sets in. Tree pollen from species like oak and maple remains dormant until spring, so no significant tree-related activity is expected for months to come.
