What this tree pollen level means
Low risk. Keep windows open; consider allergy meds only if sensitive.
Enjoy outdoor activities.
River-corridor trees open in late March or April, varying by valley elevation, and run into May. This month sits outside the usual tree pollen window for the Northern Rockies pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Montana allergy season guide singles out sagebrush, flowering late on the dry benches, over a grass summer of timothy, orchard grass, bluegrass and ryegrass.
