Mediterranean climate. Summers are hot and dry (28–36°C, June–August) with little rain and intense sunshine. Heat rarely disrupts flights but can make the terminal uncomfortable. Winters are mild (5–13°C) with rain primarily from November through February. Snow in Rome is rare, occurring once every few years, but when it falls the city and airport are largely unprepared. Even light accumulations cause significant disruption.

Spring and autumn are the most pleasant seasons (15–23°C). Sirocco winds from the Sahara occasionally bring warm dusty air and reduced visibility in spring. FCO has little fog risk and generally good flying weather compared to northern European hubs.
