Durham Tree Pollen Count: 5-Day Forecast

Pollen Atlas models the daily detail as an overall index: day-by-day splits by individual pollen type are not part of the modelled data, so this table shows Durham’s overall trend across the week. Today’s tree pollen reading is the headline above.

Species driving Durham’s tree pollen

The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

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.
