Philadelphia-South Jersey area pollen and mold spores

Today concludes our 2015 Pollen and Outdoor Mold Spore Reports. As colder temperatures overnight continue to eliminate pollen producing plants, pollen levels will fall and become nonexistent. Outdoor mold spores do stay present until there is snow cover on the ground. Reports will resume mid-March 2016.

  • GRASSES: Not Seen
  • MOLDS: Very High
  • RAGWEED:  VEry Low
  • OTHER WEEDS: Very Low
