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 Utah allergy season guide singles out planted elm, maple, ash and poplars in spring, and chenopod and sagebrush-country weeds at the close.
