Average weather, temperature, rainfall, sunshine hours
The climate of Monza is
moderately continental, with cold, damp winters and hot, muggy summers.
The city is the capital of the province of Monza and Brianza and is located in the north-eastern part of the conurbation of Milan.
Winter, from December to February, is cold, damp and gray. There are periods in which the temperature remains around freezing (0 °C or 32 °F) even in the daytime, especially in December and January, and the sky remains overcast for long periods.
Typically, by the second half of February, the temperature tends to increase, and highs exceed quite often 10 °C (50 °F).
Fog, which was once common, has become rarer, and is formed only in periods with Atlantic high pressure.
The wind is usually weak or absent, except when the
föhn blows, a warm, dry wind that comes down from the Alps and is able to bring clear skies and good visibility. When the föhn blows, the temperature can exceed 15 °C (59 °F) even in the middle of winter. In January 2007, it reached 20 °C (68 °F).
Snow in Monza usually falls at least once every year, although it tends to melt soon enough. On average, around 25 centimeters (10 inches) of snow fall per year (while in Milan, due to the heat island of the city, less than 20 cm or 8 in fall). In the great snowfall of 13-17 January 1985, more than one meter (40 in) of snow fell.
Every now and then,
cold air masses from Eastern Europe can bring quite intense frosts, though the temperature rarely drops below -10 °C (14 °F). However, the temperature reached -13 °C (8.5 °F) in February 2012.
Summer, from June to August, is hot and muggy, and generally sunny, at least in the morning. The heat is felt because of high humidity and poor to no wind.
Sometimes, an Atlantic front, able to bring cool and rainy weather, can affect this area even in summer; more often, on sunny days, thunderstorms can erupt in the afternoon or evening.
During
heat waves, which are becoming increasingly more frequent, the temperature can reach or exceed 35 °C (95 °F). In August 2017, the temperature reached 39.5 °C (103 °F).
Best Time
The
best period to visit Monza is that of spring and early summer, and in particular, from mid-April to mid-June. September, too, is a good month. However, you have to take into account some rainy days in both periods.
Summer can be hot, although some days can be acceptable, especially in June. In summer, and sometimes in May, sudden thunderstorms in the afternoon or evening must be put into account.
