7-Day Pollen Forecast for Rome
Pollen Season in Rome
Rome's Mediterranean climate creates a pollen season that starts earlier and finishes later than northern European cities. Cypress trees — lining roads throughout Lazio and Tuscany — release their pollen from January through March, causing significant problems for the many Romans who are sensitised to cupressaceae. Olive pollen peaks in May across central Italy, while grass pollen from the Campagna Romana agricultural plain dominates from April to June. Parietaria (pellitory-of-the-wall) is a particularly problematic weed in Rome, growing on ancient walls, ruins, and urban pavements — it has an exceptionally long season from spring through October. Summers are hot and dry, which reduces pollen but increases urban pollution that can intensify allergy symptoms. About 25% of Romans suffer from allergic rhinitis.
- Cypress pollen begins in January — if you visit Rome in winter and experience eye and nose symptoms, cupressaceae allergy may be responsible.
- Parietaria grows on Roman walls and ruins and pollinates almost year-round; it is a common sensitiser that many visitors overlook.
- Afternoon sea breezes from the Tyrrhenian coast can push grass pollen from the Campagna Romana into the city — symptoms often worsen in the evening.
