<P> On the coast from Ravenna to Venice and Trieste, snow falls more rarely: during cold spells from the east, the cold can be harsh but with bright skies; while during the snowfalls that affect Northern Italy, the Adriatic coast can see a milder Sirocco wind which makes snow turn to rain--the mild effects of this wind often disappear just a few kilometres inside the plain, and sometimes the coast from Venice to Grado sees snow while it is raining in Trieste, the Po River mouths and Ravenna . Rarely, the city of Trieste may see snow blizzards with north - eastern winds; in the colder winters, the Venice Lagoon may freeze, and in the coldest ones even enough to walk on the ice sheet . </P> <P> Summer is usually more stable, although the northern regions often have thunderstorms in the afternoon / night hours and some grey and rainy days . So, while south of Florence the summer is typically dry and sunny, in the north it tends to be more humid and cloudy . Spring and Autumn weather can be very changeable, with sunny and warm weeks (sometimes with Summer - like temperatures) suddenly broken off by cold spells or followed by rainy and cloudy weeks . </P> <P> In the north precipitation is more evenly distributed during the year, although the summer is usually slightly wetter . Between November and March the Po valley is often covered by fog, especially in the central zone (Pavia, Piacenza, Cremona and Mantua), while the number of days with lows below 0 ° C (32 ° F) is usually from 60 to 90 a year, with peaks of 100--110 days in the mainly rural zones . Snow is quite common between early December and early March in cities like Turin, Milan and Bologna, but sometime it appears in late November or late March and even April . In the winter of 2005--2006, Milan received around 0.75--0.8 m (2 ft 5.53 in--2 ft 7.50 in) or 75--80 cm (29.5--31.5 in) of fresh snow, Como around 1 m (3 ft 3.37 in) or 100 cm (39.4 in), Brescia 0.5 m (1 ft 7.69 in) or 50 cm (19.7 in), Trento 1.6 m (5 ft 2.99 in) or 160 cm (63.0 in), Vicenza around 0.45 m (1 ft 5.72 in) or 45 cm (17.7 in), Bologna around 0.3 m (11.81 in) or 30 cm (11.8 in), and Piacenza around 0.8 m (2 ft 7.50 in) or 80 cm (31.5 in) </P> <P> Summer temperatures are often similar north to south . July temperatures are 22--24 ° C (71.6--75.2 ° F) north of river Po, like in Milan or Venice, and south of river Po can reach 24--25 ° C (75.2--77.0 ° F) like in Bologna, with fewer thunderstorms; on the coasts of Central and Southern Italy, and in the near plains, mean temperatures goes from 23 ° C to 27 ° C (80.6 ° F). Generally, the hottest month is August in the south and July in the north; during these months the thermometer can reach 38--42 ° C (100.4--107.6 ° F) in the south and 32--35 ° C (89.6--95.0 ° F) in the north; Sometimes the country can be split as during winter, with rain and 20--22 ° C (68.0--71.6 ° F) during the day in the north, and 30--40 ° C (86--104 ° F) in the south; but, having a hot and dry summer does not mean that Southern Italy will not see rain from June to August . </P>
