Unlike the people shown in the photo, you can't wear t-shirts this time of year, but you can catch some great travel bargains. December temperatures average 56°F during the day. Rain averages 4.80 in. - January and February temps are about the same, but rainfall is less, especially in February. Christmas in Rome is beautiful, and going in January and February is a great way to stave off those winter blues. Added bonus: All that walking is a good way to get rid of those extra pounds you put on during the holidays. Travel Tip: Pay extra for a personal guide. And pay even extra for a good one. If you go this time of year, lines won't be so long, but in the warmer months, the lines are blocks long. A personal guide has free range, by-passing the lines. We are looking to go back next September when the day temps are79°F.
