Travel tips for September

September is a good time for families visiting Sicily. While autumn begins in Central Europe, Sicily still enjoys full late summer with temperatures around 27 °C (81 °F), swimmable sea at about 26 °C (79 °F), and a relaxed, peaceful atmosphere.

Late summer by the sea – good for children

In September, beaches are much quieter than in the peak season—suited to families with children who want to splash in the calm sea, collect shells, or enjoy long beach walks. Family-friendly shallow beaches include San Vito Lo Capo, Fontane Bianche, and Marina di Ragusa.

Festive experiences for the whole family

September is also a month of festivals in Sicily: village feasts, grape harvest festivals, and religious celebrations welcome everyone. Many events are ideal for families, featuring live music, parades, children’s activities, and authentic Sicilian food.

Sagra dell’Uva (Milo): A traditional grape festival in the Etna region, with grape stomping, parades, and tastings—fun for kids and adults alike.
Festa della Madonna Addolorata: Religious processions and festive markets take place in towns across Sicily during mid to late September.
Wine festivals in Val di Noto: While adults enjoy tastings and live music, there are also plenty of family-friendly spaces and children’s entertainment.
Cous Cous Fest in San Vito Lo Capo: An international culinary festival by the sea. Families can sample couscous dishes from around the world, enjoy beach concerts, street performers, and cooking shows with activities suitable for all ages.

Hiking, nature & culture in a gentle climate

The mild September weather is well suited to family-friendly excursions. Explore the natural beauty of Alcantara Gorge, walk through lava landscapes on Mount Etna, or visit archaeological parks like Selinunte—adventures for curious young minds!
