The winter, from December to February, is quite cold, and characterized by sunny periods alternating with rainy periods.
Temperatures are typically above freezing, but the city is exposed to cold air masses from the northeast, which can lead to periods of snow and frost. Snowfalls can also be abundant. On average, about one meter (40 inches) of snow falls per year. Snow can also fall in March, and occasionally even in April.
The coldest record is -11 °C (12 °F), recorded in February 1956, January 1963 and January 1968. On other occasions, the temperature dropped to -10 °C (14 °F) in December 1961, January 1979 and at the end of February 2018. In January 2017, there was a day with a minimum -9 °C (16 °F) and a maximum -8 °C (17.5 °F). A daily maximum of -8 °C (17.5 °F) was also recorded in February 1956, while in January 1963, the maximum was -9 °C (16 °F) for a couple of days.
In March, the temperature dropped to -9.5 °C (15 °F) in 1963, -8 °C (17.5 °F) in 1971, -8.5 °C (16.5 °F) in 1987, and -7.5 °C (18.5 °F) in 2005.
The summer is warm to hot and sunny, with rare rainy days and some thunderstorms.
Generally, the heat is not excessive, and definitely more pleasant than in the plains of central-southern Italy, also because the humidity is not high.
Sometimes, however, there can be very hot periods due to the sirocco, which are becoming more frequent due to global warming, and in which the temperature can reach and exceed 35 °C (95 °F). In July 1983, the temperature reached 37.5 °C (99.5 °F), while in July 2023 (when there was one day with a low of 30 °C or 86 °F), it reached 38.2 °C (100.7 °F). In August 2017, there were 7 days with highs of 37/38 °C (98.5/100.5 °F), and the minimum was 28 °C (82.5) for a couple of days.
On average, there are around 2,110 sunshine hours per year. The sun shines therefore less often than along the coasts of central and southern Italy. Here are the average sunshine hours per day.
