Pollen and allergies — Genova
Genoa is a coastal city squeezed between the Ligurian Sea and the Apennines. The distance between the sea, slopes and valleys can produce different conditions on the same day; wind and humidity are especially important when planning outdoor time.
Periods and allergens to watch
- Late winter and spring: alder, birch and other trees can begin the season.
- Spring: grasses occur in meadows, hillsides and open areas.
- Spring to summer: olive and other oleaceous plants are part of the Ligurian setting, but this is not a neighbourhood measurement.
- Summer and late summer: mugwort and ragweed may follow roads, construction sites and disturbed ground.
Genoa’s data are CAMS forecasts modeled through Open-Meteo, not local measurements from this service. The approximately 11 km resolution is useful for a broad trend but cannot describe every valley or harbour breeze. Mediterranean taxa such as cypress and parietaria are not among the six CAMS variables displayed here.
A daily route can move from sea level to a hillside within minutes. A sea breeze, a sheltered slope or a valley may therefore produce a different personal experience. Before running, hiking or working outdoors, combine the trend with observed wind and humidity. The page helps with preparation, but it does not certify the air in every neighbourhood.
