Species driving Bartelso’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 34 (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.

Ragweed builds from mid-August, peaks in September, and ends at the first frost. This month sits outside the usual ragweed pollen window for the Midwest & Great Lakes pattern, so today’s ragweed pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Illinois allergy season guide singles out the classic tree, grass and ragweed sequence at full strength, with mold as a Chicago co-headliner.
