Pollen and allergies — Ancona
Ancona is the capital of the Marche, a port on the Adriatic folded between the sea and the hills of Mount Conero, just south of the city. The sea breeze refreshes the air over the coastal districts, while just beyond the centre the Marche olive groves climb the slopes: olive is one of the region's main allergens, alongside the grasses that dominate meadows, farmland and roadside margins. Winters are milder than in the inland Apennines, but the season stays clearly marked.
Periods and allergens to watch
- Spring: grasses in urban meadows, ditches and the margins of hillside farmland.
- May and June: olive, the star of the hills around Ancona and much of the Marche hinterland.
- Summer: coastal ventilation helps disperse pollen; on still days it collects on sheltered slopes.
- Late summer: mugwort grows in grassy margins; ragweed, historically less widespread in central and southern Italy, still appears in the modeled data.
Ancona 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 cypress or parietaria, both present in the regional landscape, or every local species.
The breeze rising from the port and the Passetto changes the reading between coast and hill: along the seafront the air renews itself, while in the higher quarters and the countryside behind the city pollen can linger. A trip to the Conero or into the surrounding countryside 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.
