Yonkers, situated in the lower Hudson Valley just north of New York City, has a humid continental climate that produces a long, layered allergy season stretching from early spring through late fall.
Tree pollen kicks things off in March and typically peaks in April and May, driven by the region's dense deciduous canopy of oak, maple, birch, ash, hickory, sycamore, and cedar, with oak and birch generating some of the most intense spring counts.
As tree pollen wanes, grass pollen rises in mid-May and lingers through July, with timothy, orchard, Kentucky bluegrass, and ryegrass dominating local lawns and roadsides. The late-spring overlap between tree and grass pollen often intensifies symptoms for multi-sensitive sufferers.
By mid-August, weed pollen takes over and peaks through September and into October, led by ragweed—which thrives along the Hudson shoreline and disturbed lots—alongside mugwort, lamb's quarters, and pigweed.
Non-pollen triggers are also significant: humid summers promote outdoor mold spores, while the city's older housing stock and proximity to I-87 and NYC traffic contribute to indoor dust mite exposure and particulate pollution that can worsen reactions.
Overall, Yonkers presents a moderate-to-high allergy burden defined by tree-heavy springs, ragweed-driven falls, and persistent humidity-related mold.
