When people think of Sardinia, the imagination immediately turns to summer: crowded beaches, scorching sun, and lively resorts. But the island has another side, more intimate and authentic: autumn.
Alghero in autumn is the perfect expression of this hidden charm. Located on the north-west coast of Sardinia, it combines the sea, nature, Catalan traditions, and a unique historical and cultural heritage.
If you’re wondering what to do in Alghero in September, October and November, this guide will take you through the mild climate, local events, nearby villages, traditional dishes, and unforgettable experiences.
Perfect climate and warm sea: the summer that never ends
One of the main reasons to choose Alghero in autumn is its mild and sunny climate. In September and October, daytime temperatures range from 22°C to 28°C, ideal for enjoying the outdoors without the summer heat.
The sea remains pleasantly warm until late October, making it perfect for swimming, water sports, or simply relaxing on almost-deserted beaches.
The autumn light enhances the landscape: the colors of the sea, reflections on the rocks, and sunsets become spectacular natural shows.
A journey through history: Alghero and nearby villages
Alghero’s old town
Walking through the historic center feels like stepping back in time. The Aragonese walls, the sea bastions, the Porta Terra Tower, cobbled alleys, and wrought-iron balconies tell stories of centuries past.
In autumn, you can explore at your own pace, visit churches, museums, and craft shops without the crowds, and enjoy the slow rhythm of the city.
Bosa: colorful houses and riverside charm
Less than an hour from Alghero, along one of Sardinia’s most scenic roads, lies Bosa. This town on the Temo river looks like a painting come to life: pastel-colored houses, stone bridges, and the medieval Malaspina Castle overlooking the valley.
In autumn, Bosa is even more enchanting, wrapped in soft light and perfect for a day trip with a glass of its famous Malvasia di Bosa wine.
Castelsardo: a jewel by the sea
Heading north, you’ll find Castelsardo, one of Italy’s most beautiful villages. Perched on a promontory, it offers postcard views. Its steep lanes, artisan workshops, and breathtaking panoramas over the Gulf of Asinara make it an unmissable stop.
Events and traditions: the Feast of San Michele
The highlight of autumn in Alghero is undoubtedly the Feast of San Michele, the city’s patron saint, celebrated on September 29th.
The celebrations begin days earlier and fill the historic center with:
- live concerts and theater shows,
- craft and food markets,
- children’s activities, art installations, and street performances.
Sport also plays a big role: the marathon and half marathon are among the most anticipated events, offering runners the unique thrill of racing along the bastions and through the olive groves with the sea as a backdrop.
Sport and nature: an outdoor paradise
Autumn is the perfect season for nature lovers and outdoor activities. The temperatures are ideal, and the landscapes take on warm, fascinating tones.
