Weather and climate in Turin (Piedmont)

In Turin, the capital of Piedmont, the climate is moderately continental, with cold, damp winters and hot, muggy summers.
The city is located at 250 meters (800 feet) above sea level, at the foot of the Alps, and along the Po River. Because of its position, in summer, it is not as hot as the rest of the Po valley, while in winter, it is a little less foggy.
At the Caselle Airport, the average temperature of the coldest month (January) is 3.2 °C (37.8 °F), that of the warmest month (July) is 23.2 °C (73.8 °F). Here are the average temperatures.

Precipitation is quite abundant, in fact, it amounts to 950 millimeters (37 inches) per year. The least rainy season is winter, while the wettest periods are late spring, mainly because of afternoon thunderstorms (May is the wettest month), and autumn. However, thunderstorms can occur in summer as well.
Here is the average precipitation.

Winter, from December to February, is cold and damp. The sky is often cloudy, and fog may form in anticyclonic periods, although less frequently than in Milan and other areas of the Po Valley. Around midday, the sun can come out.
There is a moderate amount of rainy days, although winter is the least rainy season.
The wind is generally weak or absent, except when the föhn blows, a warm and dry wind that comes down from the Alps and is able to bring clear skies and good visibility; in these cases, the temperature can reach or exceed 15 °C (59 °F) even in winter. In January 2007, it reached 25 °C (77 °F), while in January 2008, it reached 23 °C (73.5 °F).
Snow in Turin generally falls at least once every year, although it is seldom very abundant; in amounts on average to 25 centimeters (10 inches) per year. However, here are some heavy snowfalls that occurred after the war: 50 cm (20 in) in January 1954, 35 cm (13.5 in) in January 1985, 45 cm (17.5 in) in February 1986, 55 cm (21.5 in) in January 1987, and 40 cm (15.5 in) in March 1993.
However, Piedmont, being enclosed in the mountains, can see snow even with the sirocco, because the cold air resists in the lower layers more than in other Italian regions.
Every now and then, cold air masses from Eastern Europe can bring frosts, more or less intense. The coldest record, -22 °C (-7.5 °F), was recorded in February 1956. Thereafter, the temperature reached -15 °C (5 °F) in January 1960 and in January 1963, -13 °C (8.5 °F) in December 1963, -15.5 °C (4 °F) in January 1971, -13 °C (8.5 °F) in January 1985 and December 2009, and -14 °C (7 °F) in February 2012.

Spring in Turin is initially an unstable season, when the first mild days alternate with the return of cold periods. However, it gradually becomes more enjoyable, especially from mid-April to late May, when there are many nice days, with mild or pleasantly warm temperatures during the day, although thunderstorms can break out in the afternoon or in the evening.
However, Atlantic depressions able to bring rainfall are still quite frequent.

Summer, from June to August, is hot and muggy, and generally sunny. Even though the wind is generally weak, the heat is more often bearable than in the rest of the Po Valley because the temperature is a bit lower, but also because of thunderstorms, which can be accompanied by wind gusts, and affect the city quite frequently, especially in the afternoon and in the evening.
There is still some chance of some Atlantic disturbances, which can bring some pretty cool and rainy days even in midsummer (but especially in June and late August).
However, even in Turin there may be very hot periods , in which the temperature can reach or exceed 35 °C (95 °F). The highest temperature, 37 °C (98.5 °F), was recorded in late June 2019, in July 1952 and July 2022, and in August 2003.

Autumn gives some nice days in September, and sometimes in early October, then quickly becomes gray and rainy. The first cold days usually occur in November.



The amount of sunshine in Turin is not very good from mid-October to February, when the sun comes out quite rarely (but it goes better than in Milan). However, the sun shines for a moderate number of hours in spring, and it's frequent in summer, except during the rare rainy days, and during the more frequent thunderstorms occurring in the afternoon or in the evening. On average, there are nearly 2,000 hours of sunshine per year. Here are the average sunshine hours per day.

On the hills that lie to the east of Turin, beyond the Po River, the climate is milder, in fact, in winter, they are often above the layer of cold air that stagnates in the Po Valley (but snowfalls are more abundant), while in summer, they are cooler because of the higher altitude.
For example, here are the average temperatures of the Bric della Croce station, 700 meters (2,300 feet) above sea level, in the municipality of Pecetto Torinese.

Best Time

The best times to visit Turin are spring and early summer, 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 less frequently than in the rest of the Po valley, actually, there can be a good number of days with acceptable temperatures, especially in June. You have to take into account, in late spring and summer, sudden thunderstorms in the afternoon or in the evening.
