Map from Google - Palermo

In Palermo, the capital of Sicily, the climate is Mediterranean with very mild and rainy winters, and hot, sunny summers.
The city is exposed to the sirocco, the wind from Africa, which is able to raise the temperature by several degrees (it is possible to exceed 20 °C or 68 °F in winter, and to touch or exceed 40 °C or 104 °F in summer), but also to the cool Mistral, which blows from Sardinia. In summer, when good weather prevails, the sea breeze tempers the heat.
During the winter, it is rarely very cold, however, there may be cold, windy and rainy days, with highs around 10 °C (50 °F). Very rarely, in the inner areas of the city there may be a snowfall. The cold records are around 0 °C (32 °F).
