The sea is typically calm. Its waters are clear and inviting. This makes July a prime window for days spent along the coastline or exploring the nearby archipelago. The local rhythm follows the reliable pattern of market mornings, languid beach afternoons, and evenings where the scent of grilling seafood and the murmur of conversation fill the air.
