Species driving Hornsund’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 0.6 (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.

Plant detail returns here automatically on any day the feed includes it.
What this ragweed pollen level means
Low risk. Keep windows open; consider allergy meds only if sensitive.
Enjoy outdoor activities.
Mugwort runs through August, and ragweed is scarce at these latitudes — the late window is short and light. This month sits outside the usual ragweed pollen window for the Nordic & Baltic North pattern, so today’s ragweed pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. No Svalbard allergy season guide is published yet, so the seasonal context here follows the Nordic & Baltic North regional pattern.
