Pollen Count in Paterson, NJ

Paterson, NJ sits in the humid continental climate zone of northern New Jersey, where distinct seasons and proximity to the Passaic River Valley produce a prolonged and varied allergy calendar.

Tree pollen typically kicks off the season in early March and peaks through April and into May, with oak, maple, birch, cedar, ash, and sycamore among the dominant local contributors. As tree counts taper, grass pollen surges from mid-May through July, driven largely by timothy, Kentucky bluegrass, orchard grass, and ryegrass common to regional lawns and open lots.

There is often a notable overlap in late May and early June, when lingering tree pollen combines with rising grass counts to intensify symptoms.

Weed season follows in August and extends through the first hard frost in October, dominated by ragweed—a major regional trigger—alongside lamb's quarters, pigweed, and mugwort.

Beyond pollen, Paterson's humid summers and older urban housing stock encourage indoor and outdoor mold growth, while dust mites remain a year-round concern. Vehicle emissions and industrial particulates from the broader NYC metro area can further aggravate respiratory sensitivity.

Overall, Paterson's allergy profile is defined by a long, layered pollen season, significant ragweed exposure, and persistent mold and pollution pressures.
