Pollen Count & Forecast for Genoa

Genoa’s spring allergy season (February–May) is dominated by Cypress (Cupressus) and Pellitory-of-the-wall (Parietaria); Cypress frequent on Appennino Ligure hills and Parco di Nervi; Pellitory-of-the-wall grows on ancient city walls. Olive (Olea europaea) blooms in hillside groves; Holm Oak (Quercus ilex) grows in Parco del Peralto. Summer (May–August) has high Grass (Poaceae) pollen levels, originating from Bisagno and Polcevera riverbeds.

Steep hills and coastal winds trap allergens against the mountains; narrow Caruggi alleys restrict airflow. Autumn and winter see elevated Mould (Alternaria, Cladosporium) spore counts, from humid Mediterranean valleys and damp port areas.
