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.

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). 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.
