Pollen, Mold, & Ragweed Count for the the Delaware Valley
Pine tree pollen returns to dominate today's count at over 60% of total tree volume. Grass pollen hits very high levels for the first time this season! Outdoor mold spore levels are decreased by half but remain very high and still may cause moderate to severe symptoms. Tree pollen is very high. Mold spores are very high. Ragweed pollen is not found. Grass is very high. Other weeds are very low.

The Asthma Center is the region’s pollen count source
Certified by the National Allergy Bureau (NAB), The Asthma Center is the region’s only official source for today’s pollen, mold, and ragweed counts. We operate two official monitoring stations in the Delaware Valley, one in Center City, Philadelphia and the other in Mt. Laurel, New Jersey.
During the pollen season, The Asthma Center team collects, analyzes, and publishes the region’s official daily pollen count. We often share our research with local and national media (check out Dr. Don Dvorin on CBS below!), and use our expertise about local pollen conditions to understand the air you breathe so we can treat you better!
During the spring, summer, and fall, we post daily pollen counts to our website, the NAB website, and to our pollen count subscribers.
