Pollen Count & Forecast for Palermo

Palermo’s spring season (March-June) is dominated by Pellitory and Olive pollen; Pellitory-of-the-wall (Parietaria judaica) prolific on stone walls across the city centre; Olive (Olea europaea) dense within Parco della Favorita and surrounding hillsides. Cypress (Cupressus sempervirens) contributes significantly from Santa Maria dei Rotoli cemetery. Summer (May-July) sees high Grass (Poaceae) pollen levels, originating from the Oreto River valley and slopes of Monte Pellegrino.

The surrounding mountains and coastal winds can trap pollen, leading to localised high concentrations. Autumn and winter see high Mould (Alternaria, Cladosporium) spore counts, from damp city environments and the humid Conca d’Oro.
