Trees open in late March and build to an oak-led peak in May. This month sits outside the usual tree pollen window for the Northeast pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The New Jersey allergy season guide singles out oak, the spring heavyweight statewide, with maple sharing the stage and birch earning a real billing in the northwestern hills.
