Climate in Fiumicino (Lazio)

The climate of Fiumicino is Mediterranean, with mild, rainy winters and hot, sunny summers.
The city is located on the Roman coast, about 25 km (15 mi) away from the center of Rome, and north of the delta of the Tiber, beyond which we find the lido of Ostia. Nearby we find the Leonardo da Vinci international airport, while on the coast to the north is Focene.
The climate is similar to that of Rome, but there are some small differences. Winter is a little milder, but during periods of bad weather, the southwest wind, the libeccio, can be stronger. Generally, the temperature does not drop below -5 °C (23 °F) even during the coldest periods. In January 1985, the temperature dropped to -8 °C (17.5 °F), against -10/-11 °C (12/14 °F) at the Rome airports.
Summer is less hot, and afternoon thunderstorms from the Apennines are a little rarer. At the end of June 2022, the heat record was broken with 39 °C (102 °F).
