What this grass pollen level means

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

Enjoy outdoor activities.

Grasses build from spring and peak from April into June, earlier in the south. This month sits outside the usual grass pollen window for the Mediterranean pattern, so today’s grass 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.
