Species driving Hartland’s tree pollen

Low risk. Keep windows open; consider allergy meds only if sensitive.

Enjoy outdoor activities.

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 Maine allergy season guide singles out birch, a signature spring pollen, released with maple and oak in a rapid April and May burst.
