Milan experiences a Humid subtropical climate (Köppen climate classification Cfa) with some continental characteristics. This is typical of Northern Italy's inland plains, where hot, humid summers and cold, damp winters prevail, unlike the Mediterranean climate characteristic of the rest of Italy.
Average temperatures in city center are ?3 to 4 °C (39 °F) in January and 19 to 30 °C (86 °F) in July. Snowfalls are relatively common during winter, even if in the last 15-20 years they have decreased in frequency. The historic average of Milan's area is between 35 and 45 cm (16"/18"); single snowfalls over 30-50 cm in 1-3 days happen periodically, with a record of 80-100 cm during the famous snowfall of January 1985. Humidity is quite high during the whole year and annual precipitation averages about 1000 mm (40 in). In the stereotypical image, the city is often shrouded in the heavy fog characteristic of cold seasons in the Po Basin, although the removal of rice paddies from the southern neighbourhoods, the urban heat island effect and the reduction of pollution from factories have reduced this phenomenon in recent years, at least in the city centre. Wind is generally absent. In spring, though, gale-force windstorms can happen, generated either by Tramontana blowing from the Alps or by Bora-like winds from northeast. Such windstorms often cause damages and injuries.
