Species driving Chavannes-le-Chêne’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 7 (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.
Mugwort and ragweed build from August, peak in September, and are ended by the first hard frost. This month sits outside the usual ragweed pollen window for the Continental West pattern, so today’s ragweed pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. No Switzerland allergy season guide is published yet, so the seasonal context here follows the Continental West regional pattern.
