Pollen and allergies — Catania
Catania stretches along the Ionian coast at the foot of Mount Etna, between the fertile Simeto plain and the sea. Citrus groves, olive orchards and almond trees shape the countryside, while in the city low walls, gardens and vacant ground host vegetation that keeps flowering for much of the year in the warm climate. The circulation around the volcano and the Ionian sea breezes move air between plain and slopes, stretching the pollen season well beyond much of the peninsula.
Periods and allergens to watch
- Spring: grasses and olive lead the season across the Simeto plain and the Etna slopes.
- Late spring and summer: olive continues with the heat, while grasses stay active along roadsides and irrigated meadows.
- Summer: the long warm season keeps pollen circulating in the greener districts; the sea breeze softens but does not erase it.
- Almost year-round: parietaria, typical of walls and courtyards, can flower well outside the usual season in Catania's climate.
Catania uses CAMS through Open-Meteo. Concentrations are modeled, not measured locally by this service, at approximately 11 km resolution. The forecast displays alder, birch, grasses, mugwort, olive and ragweed; it does not automatically cover parietaria, which matters a great deal in the city, or every regional species.
Ionian breezes and the winds that flow down from Etna move pollen between districts and countryside: in the morning the air arrives from the sea, in the afternoon it climbs toward the slopes, and the reading can change fast. An afternoon toward the university district or through the historic markets may not match the city-centre value. Treat the model as a guide for the area and check real conditions before spending a long time outdoors.
