Jersey City Pollen Report
Jersey City shares the metro New York allergy calendar: oak and birch bury the region each spring, grasses carry the summer, and ragweed fills vacant lots and field edges every fall. The Hudson corridor's humidity keeps mold in play through the warm months, and the dense urban landscape traps pollen between buildings.
