When people think of Sardinia, they usually picture summer: crowded beaches, scorching sunshine and busy tourist destinations. But the island has another, more intimate and authentic side: autumn.

Alghero in autumn is the perfect expression of this quieter charm. Located on Sardinia’s north-west coast, the city combines beautiful coastlines, 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 introduce you to the weather, local events, nearby villages worth visiting, traditional dishes and plenty of experiences to enjoy.

Mild Weather and Warm Seas: Summer That Lasts a Little Longer

Here are some of the most beautiful beaches to enjoy without the summer crowds:

  • Maria Pia, with its white sand and shady maritime pine trees.
  • Le Bombarde, loved for its crystal-clear water.
  • Mugoni, sheltered from the wind and surrounded by the natural beauty of Porto Conte Regional Park.
