Alder and hazelnut can start in January west of the Cascades, with maple and oak following through April and May. This month sits outside the usual tree pollen window for the Pacific Northwest pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Oregon allergy season guide singles out alder and hazelnut early, then the Willamette Valley’s seed grasses.
