Geography and topography
Monza is located in the high plains of Lombardy, between Brianza and Milan, at an altitude of 162 metres (531 feet) above sea level. It is 15 kilometres (9 mi) from the centre of the region's capital, although when considering the cities borders, they are separated by less than 5 km (3 miles). Monza is about 40 km (25 mi) from Lecco and Como. Monza shares its position with Milan in the same metro area, and is a big part of its new province.
Monza is crossed from north to south by the River Lambro. The river enters Monza from the north, between Via Aliprandi and Via Zanzi streets. This is an artificial fork of the river, created for defensive purposes in the early decades of the 14th century. The fork is known as Lambretto and it rejoins the main course of the Lambro as it exits to the south, leaving Monza through the now demolished ancient circle of medieval walls. Another artificial stream is the Canale Villoresi, which was constructed in the late 19th century.
Monza has a typical submediterranean climate of the Po valley, with cool, short winters and warm summers; temperatures are very similar to nearby Milan, averaging 2 °C (36 °F) in January, the coldest month, to about 23 °C (73 °F) in July, the warmest. Precipitation is abundant, with most occurring in the autumn and the least in winter and summer; despite this, the city and surrounding area usually doesn't suffer drought in any season.
