Alassio occupies a wide, sheltered bay on the western Italian Riviera between Capo Mele to the east and Capo Santa Croce to the west. The town’s position at the foot of the Maritime Alps, facing due south across the Ligurian Sea, gives it a warm-summer Mediterranean climate (Koppen Csa) with hot, dry summers and mild, wetter winters. Annual precipitation averages 830 millimetres, concentrated in autumn, while summer months see as little as 15 millimetres of rain. The bay’s shallow, sandy bottom warms quickly: sea temperatures reach 25 degrees Celsius (77 Fahrenheit) in August and stay above 18 degrees Celsius (64 Fahrenheit) from June through October, giving Alassio one of the longest swimming seasons on the Ligurian coast.
