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 Nevada allergy season guide singles out mulberry, the headline pollen of the desert spring, with olive and ash.
