January weather forecast
Italy

January is firmly entrenched in the heart of Italy's winter season. The variance in geography and topography means the month offers different climatic experiences depending on where you find yourself.

In the northern Alpine region, temperatures often plummet to their lowest, with averages remaining below -17.8°C (0°F) in certain areas. It's in these parts, especially at elevations above 2000 meters, where the country experiences its most substantial snowfall, often exceeding 5080mm (200"). The snow-capped Alps present a picturesque landscape, making it a haven for winter sports enthusiasts.

The central region, including cities like Florence and Milan, tends to be milder compared to the northern extremes. However, it is not uncommon for these areas to witness cold snaps, and fog frequently blankets regions like the Po Valley, with Milan's airport being notably impacted.

Southern Italy, on the other hand, experiences milder winters. January temperatures in the south rarely drop below 4.4°C (39.9°F), making it noticeably warmer than its northern and central counterparts. Coastal areas and islands such as Sicily and Sardinia maintain a Mediterranean climate, though with cooler and rainier conditions compared to the warmer months.

When comparing January to its adjacent months, it stands as one of the coldest. December, while also being chilly, often has milder temperatures. In contrast, February, though still cold, usually indicates the beginning of a transition phase as Italy moves towards the early inklings of spring.

Noteworthy is the record for Italy's all-time lowest temperature, set in January: a bone-chilling -49.6°C (-57.3°F), recorded at Busa Fradusta, Pale di San Martino. This extreme illustrates the potential cold that the country's high-altitude regions can experience during this winter month.
