Rome Weather in January
Planning a trip to Rome in January? Here's what the weather is really like during the coldest month of the year — and one thing travelers often get caught off guard by.
January is the coldest month of the year in Rome, though it's still relatively mild compared to other parts of Europe. Highs range from the upper 40s to upper 50s°F, with the end of the month solidly in the 50s. Lows can get chilly — averaging around 33 to 43°F — with cold nights at the start of the month and gradual warming toward the end. Rain averages 7–10 days, mostly cold wintry rain from winter systems that make it over the Alps rather than thunderstorms.
Snow is rare in Rome, only happening every 5 years or so. The main alert to keep in mind is the cold nights — Rome is close to the water, so travelers sometimes don't expect it to freeze, but about 5 nights per month can actually see frost. Pack a real winter jacket. Meteorologist Ian Schwartz breaks down what to expect.
