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

Species driving Royal City’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 38 (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.

Weeds are the minor act — sagebrush and tumbleweed east of the Cascades carry into September. This month sits outside the usual ragweed pollen window for the Pacific Northwest pattern, so today’s ragweed pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Washington allergy season guide singles out alder and hazelnut from January on the west side, and timothy and sagebrush on Spokane’s continental clock.
