Juniper can arrive in late winter, and the main tree wave builds in spring — as late as April at Denver’s altitude. This month sits outside the usual tree pollen window for the Mountain West pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Idaho allergy season guide singles out sagebrush, the signature weed of the Snake River plain from August through October.
