Species driving Petroio’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 24 (Low) today.

What this tree pollen level means
Low risk. Keep windows open; consider allergy meds only if sensitive.
Enjoy outdoor activities.
Cypress opens the year in winter, hazel and alder follow early, and olive carries the spring peak from April into May. This month sits outside the usual tree pollen window for the Mediterranean pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. No Italy allergy season guide is published yet, so the seasonal context here follows the Mediterranean regional pattern.
