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 Washington allergy season guide singles out alder and hazelnut from January on the west side, and timothy and sagebrush on Spokane’s continental clock.
