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

Species driving Southwest Harbor’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 8 (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 August into September and is ended by an early first frost — earliest inland and in the north. This month sits outside the usual ragweed pollen window for the Northern New England pattern, so today’s ragweed pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Maine allergy season guide singles out birch, a signature spring pollen, released with maple and oak in a rapid April and May burst.
