Located in northwestern Italy at the foot of the Alps, at a similar latitude and altitude to Grenoble in the french Alps, Turin features a humid subtropical climate , due to its hot summers as does most of northern Italy and low intra-alpine valleys.
Winters are moderately cold and dry, summers are mild in the hills and quite hot in the plains. Rain falls mostly during spring and autumn; during the hottest months, otherwise, rains are less frequent but heavier (thunderstorms are frequent). During the winter and autumn months banks of fog, which are sometimes very thick, form in the plains but rarely on the city because of its location at the end of the Susa Valley. Snowfalls are not uncommon during the winter months, although substantial accumulation is quite uncommon.
Its position on the east side of the Alps makes the weather drier than on the west side because of the föhn wind effect.
The highest temperature ever recorded was 37.1 °C (98.8 °F), and the lowest was −21.8 °C (−7.2 °F).
