The climate in Reggio Emilia is temperate continental, with hot rather moist summers (the temperatures can sometimes rise above 35 °C) (95°F) and fairly rigid winters with frequent frosts (the temperatures can go below -10 °C)(14°F).Precipitations are evenly distributed all year long, but October, November and April are the most rainy months, while July and January are the most arid. In the city you can rarely see snow, even though almost every year there is a period when it’s snowing. Due to the rather high temperatures, it does not settle, or if it does, the layer of snow is not very consistent.
During Autumn and Winter it is very common, especially in the areas outside the city, to encounter very thick fog, even though nowadays it is less frequent than in the past. Other meteorological phenomena that one can expect in the area is the hard rain, freezing rain during winter, and hail during summer but rarely during spring.
The area is not particularly windy and there are often days of total calm, especially during the anticyclonic phases in winter, while spring is more ventilated.[14] The most intense winds are the ones blowing from North-East (Bora) or from South-West (Libeccio). The latter, during its descent from the Northern Apennines, it sometimes tends to become a downslope wind and thus being very dry and hot. In rare and particular conditions, the downwind of the Alps, the Foehn, can reach Reggio Emilia from the North-West. In Reggio Emilia, the average annual high temperature is 18 °C (64 °F), the annual low temperature is 9 °C (48 °F), and the annual precipitation is 700 millimetres (27.56 inches)
