7-Day Pollen Forecast for Milan
Pollen Season in Milan
Milan sits in the middle of the Po Valley, ringed by the Alps and Apennines, and its notoriously still, humid air means pollen and traffic particulates hang around rather than blowing out to sea. The season opens in winter with cypress and other Cupressaceae, alder and hazel from January, often peaking in February. March and April bring birch, hornbeam and ash, and above all the London planes that line Corso Sempione, the Bastioni and countless Milanese avenues \u2014 plane pollen, plus the irritant hairs shed from the leaves, is a classic local complaint. Grasses take over from May and dominate through June, worst around the open meadows of Parco Nord, Parco Lambro, the Idroscalo, Boscoincittà and Parco delle Cave, and across the farmland and rice country beyond the tangenziali. Pellitory (Parietaria) adds a long, low-level background from spring into autumn. Most distinctive is ragweed: Lombardy, especially the north-western belt towards Legnano, Busto Arsizio and Malpensa, is Italy's ragweed heartland, giving a sharp August–September peak. Olive is negligible this far north.
- Milan's stagnant air traps pollen with traffic smog, so on high-count days that coincide with poor air quality warnings, keep windows shut and favour indoor exercise over a run along the Navigli.
- If you react in late summer, check ragweed levels before heading north-west towards Malpensa, Varese or the Legnano area, where the plant is far more abundant than in the city centre.
- Rinse your hair and change clothes after an afternoon in Parco Sempione or the Giardini Montanelli during plane and grass season, and ask a pharmacist about starting preventive measures a couple of weeks before your usual peak.
