Species driving Hargshamn’s tree pollen

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.
