Species driving Rengsjö’s grass pollen

What this grass pollen level means
Low risk. Keep windows open; consider allergy meds only if sensitive.
Enjoy outdoor activities.
Grasses own a brief early-summer peak, cresting around the first hay cutting in June and July. This month sits outside the usual grass pollen window for the Nordic & Baltic North pattern, so today’s grass 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.
