Pollen and allergies — Verona
Verona opens onto the Venetian plain at the edge of the Adige valley, with the Lessinia plateau behind it to the north and farmland running towards the Mantua area and the Polesine. In the cold half of the year fog can settle for days; in summer the plain's heat adds to the traffic in the centre. Streets and urban parks hold birches and other broadleaf trees, while meadows and fields wrap around the city.
Periods and allergens to watch
- Late winter and spring: birch and alder can open the tree-pollen calendar, with flowering climbing from the valley floor towards Lessinia.
- Spring and summer: grasses dominate meadows, roadside verges and farmland around the city.
- Summer: warm, clear days favour airborne pollen, but a storm can clear the air within hours.
- Late summer: ragweed has spread across the Venetian plains and deserves attention near disturbed ground and cultivated edges.
Verona uses CAMS through Open-Meteo. Concentrations are modeled, not locally measured by this service, at approximately 11 km resolution. The forecast displays alder, birch, grasses, mugwort, olive and ragweed; it does not automatically cover cypress, parietaria or every regional species.
The plain can hold pollen and pollutants on poorly ventilated days, while towards Lessinia altitude, vegetation and local circulation change. A walk in the Valpantena or a day at the lake does not necessarily match the city-centre value. Compare the score with your own symptoms and keep an alternative plan ready for the hours spent outdoors.
