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 Byron’s overall trend across the week. Today’s ragweed pollen reading is the headline above.

Species driving Byron’s ragweed 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: ragweed pollen reads 35 (Low) today. The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

How to read this: the “ragweed” figure on this site is the modelled weed pollen index — the weed group (ragweed + mugwort) — printed under the ragweed name the rankings use.

What this ragweed pollen level means

Low risk. Keep windows open; consider allergy meds only if sensitive.

Enjoy outdoor activities.

Sagebrush flowers from August into October and peaks in September, and the first hard frost ends it. This month sits outside the usual ragweed pollen window for the High Basins pattern, so today’s ragweed pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Wyoming allergy season guide singles out sagebrush, the state’s signature allergen, flowering from August into October and peaking in September.
