Rome enjoys a mild Mediterranean climate for most of the year but the weather can be quite different depending on the time you visit. Peak tourist season in Rome is July and August, but these months can also be very hot and sticky with temperatures up to 30°C. During the height of summer there are often more tourists than there are Romans in the city, as the locals vacate to the surrounding countryside.
We prefer visiting in May and June, when the skies are clear and the temperature is an average of 23-28°C. The weather is also pleasant in April, September and October and the city is also slightly quieter.
The winter months, particularly December, can experience higher than average rainfall. But these are also the months when you'll find the cheapest flights and hotels in Rome.
