Pollen and allergies — Milano
Milan is in the heart of the Po Valley, a broad plain where cities, farmland and river corridors meet. Traffic, still-air days and parks can change how symptoms feel, but the forecast remains an estimate for the model area rather than a reading for one neighbourhood.
Periods and allergens to watch
- Early spring: alder, birch and other trees can begin the season.
- Spring and early summer: grasses are common in meadows and farmland around the city.
- Summer: heat and dry air can help airborne particles remain suspended.
- Late summer: ragweed and mugwort deserve attention near disturbed ground and roadsides.
Milan’s forecast is modeled by CAMS through Open-Meteo, not locally measured by this service. The approximately 11 km grid does not automatically distinguish the city centre, outskirts and agricultural belt. After rain or wind, compare the score with your own symptoms and plan outdoor time cautiously.
The metropolitan belt links parks, canals, fields and heavily trafficked roads. Still weather can make stagnant air more noticeable, while a wind shift can move pollen quickly. For a visit to a green area or a trip outside the city, watch the trend and keep an alternative plan. The model is not a measurement at the exact place where you are.
Traffic and pollen are related to the day’s conditions, but they are not the same indicator.
