Alder and maple stir in late March in the south, and the burst crests through April and May — birch above all, with maple and oak — later with every mile north. This month sits outside the usual tree pollen window for the Northern New England pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The New Hampshire allergy season guide singles out birch, a signature northern allergen, flowering together with maple and oak in spring.
