Hillsborough Ragweed Pollen Count: 5-Day Forecast

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

Species driving Hillsborough’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.

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 North Carolina year. The North Carolina allergy season guide singles out oak-family pollens — not the visible pine dust, which is a weak allergen flowering in the same weeks.
