Species driving Rosersberg’s tree 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: tree pollen reads 0.6 (Low) today. The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

What this tree pollen level means

Low risk. Keep windows open; consider allergy meds only if sensitive.

Enjoy outdoor activities.

The season is compressed: alder stirs first, and birch — the region’s signature spring pollen — peaks through May into early June. This month sits outside the usual tree pollen window for the Nordic & Baltic North pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. No Sweden allergy season guide is published yet, so the seasonal context here follows the Nordic & Baltic North regional pattern.
