Swimming in Nisyros
Nisyros is a volcanic island in the Dodecanese, its circular shape formed by an ancient caldera. The coastline varies from black volcanic beaches to white pebble coves, and the island's volcanic warmth extends to its coastal waters, which tend to be slightly warmer than surrounding islands.
Wind protection on Nisyros benefits from the island's compact, circular shape and its volcanic rim, which acts as a natural wind barrier for south-facing beaches. The island is small enough that you can easily check conditions at multiple beaches in a single morning.
Swimming is best from May to October. Nisyros rewards curious swimmers — the volcanic underwater landscape creates excellent snorkelling, and the thermal springs near some beaches add a unique element to the swimming experience.
