Big Sky Tree Pollen Count: 5-Day Forecast

Pollen Atlas models the daily detail as an overall index: day-by-day splits by individual pollen type are not part of the modelled data, so this table shows Big Sky’s overall trend across the week. Today’s tree pollen reading is the headline above.

Species driving Big Sky’s tree pollen

Species-level counts are not part of the modelled data Pollen Atlas publishes — the modelled index is reported per pollen type, not per species — so this section gives the type summary: tree pollen reads 0.6 (Low) today. The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

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.
