You can google and find this information online. Pick the towns and the months. Averages are available.

Early March in 2017 for six nights in Rome was 40's and damp in the morning, requiring a lightweight down jacket, stocking cap and gloves to stay toasty on my walks along the Tiber. The days would be mostly in the 50's but to a midwesterner felt like above 60, so walking around I was down to a sleeveless fleece vest over a long sleeve shirt most of the time. Evenings were just right, around 50, slight chill in the air. Only sprinkled rain once.

In other words, perfect weather. Enjoy!
