Alghero is found on the northwest side of the island of Sardinia on the sea. Alghero was built around a fortified port, and is a popular tourist resort.
As you can see from the historic temperature charts, Algherohas pleasant high temperatures pretty much all year around, although July and August can get quite warm. The precipitation chart shows the typical Mediterranean climate, with little rain in the summer and a winter rainy season which reaches a peak in November.
Beaches will be open from mid June to med September, but get busy on Ferragosta, the middle of August.
Alghero's old town is walled right up to the sea, but there are many interesting beaches around, especially around Stintino. The Grotta de Nettuno is found on the peninsula of Capo Caccia. It's a favorite place to visit; boat trips from Alghero's port depart to the grotto at regular intervals in summer, and less frequently in spring and fall. There is an hourly tour of the marine caves.
The area around Alghero is rich in evidence of the island's prehistoric culture. Nuraghe di Palmavera is the best preserved nuraghic complex in the region and the older Anghelu Ruju is a necropolis consisting of around forty burial chambers.
North of Alghero Marina is the sandy beach of Alghero, a short stroll from the historic center.
Alghero has a strong Catalan character owing to the seizing of the town by Pedro IV of Aragon in the 14th century and the Spanish colonization that followed. Catalan is heard in the streets--and if you speak Spanish there's a good chance a local will understand you.
