Species driving South Union’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 21 (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.
Ragweed runs from mid-August to the first frost. This month sits inside the ragweed pollen window for the Southeast pattern, so today’s ragweed pollen reading should be judged against that chapter of the South Carolina year. The South Carolina allergy season guide singles out oak — the pine dust filming cars in the same weeks is a comparatively weak allergen.
