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 Erie’s overall trend across the week. Today’s tree pollen reading is the headline above.

Species driving Erie’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 1 (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.

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 Colorado allergy season guide singles out juniper, arriving ahead of the local tree season, and the ragweed and sagebrush-family weeds of late summer.
