The coastal areas of Liguria, Tuscany and most of the South generally fit the Mediterranean climate stereotype (Köppen climate classificationCsa). Conditions on peninsular coastal areas can be very different from the interior's higher ground and valleys, particularly during the winter months when the higher altitudes tend to be cold, wet, and often snowy. The coastal regions have mild winters and warm and generally dry summers, although lowland valleys can be quite hot in summer. Average winter temperatures vary from 0 °C (32 °F) on the Alps to 12 °C(54 °F) in Sicily, like so the average summer temperatures range from 20 °C (68 °F) to over 30 °C (86 °F).[85]
