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

Species driving Topstone’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 18 (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.

Ragweed builds from mid-August, peaks in September, and is ended by the first hard frost. This month sits outside the usual ragweed pollen window for the Northeast pattern, so today’s ragweed pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Connecticut allergy season guide singles out oak, the spring heavyweight peaking in May, with birch alongside.
