On the whole, Italy weather and climate are pretty predictable and mild. If we take Northern Italy weather which tends to be colder than that of Southern Italy and the islands, the hottest thermometer marks are in July and August, November is the rainiest month, and January is the coldest.
For instance, the weather in Florence Italy is usually warm with average summer temperatures of around 25°C (about 77°F) and winter temperatures of about 7°C (45°F). The same pretty much applies to other Tuscany towns as well as Bologna.

The lovely city of canals has similar averages too, Venice weather in months like July is approximately 23°C (73°F) and about 3°C (37°F) in winter months such as January.

Cities that are located further north in Lombardy and Piedmont, like Milan and mountainous Turin, are normally a bit colder, with quite hot summers, rainy weather in May and November, and cold and foggy winters.

What’s for the capital, which is technically in the central part of the country, Rome weather in the summer is very warm 25-33°C (77-91°F), and in the winter the thermometer marks drop to around 8-10°C (46-50°F), still not too chilly.

July and August are considered to be not the best months for visiting Rome and Northern Italy in general as the cobblestone streets are very hot and swarming with travelers.

Hence, plan your Northern Italy travels in April-June, or September-November and enjoy the nice warm weather. Moreover, there are plenty of activities to take while traveling. Thus, make sure to make a list of your preferred activities in advance.
