What are the typical sea temperatures around Mallorca like throughout the year?

If you glance at the local fishermen’s boats moored along the port of Soller in spring, you might notice how clear and inviting the water looks—but it’s still cool for a swim. As the year progresses, the bays and coves around the island steadily warm up. In summer, waters off the north coast near Formentor or the south coast beaches like Es Trenc often hover between a comfortably warm 21°C and 27°C, ideal for snorkeling, swimming, or enjoying a boat trip along the Serra de Tramuntana coastline.

Come autumn, the sea retains a gentle warmth, especially around spots like Cala Mondragó, cooling slowly to the high teens Celsius. It’s still pleasant enough for a dip if you don’t mind the slight chill. Winter waters, particularly along Alcudia’s wide bay or near Palma, dip further, sometimes to around 12°C, a temperature that keeps most visitors onshore, though locals may brave it for an invigorating swim.

The spring months bring gradual warming as almond blossoms bloom in Valldemossa and Deia, with water temperatures rising from low teens to just under 20°C by May. This season offers quieter beaches and a softer sea, inviting those who prefer peaceful swims before the summer crowds arrive. Each season presents a different ocean mood here, complementing the island’s shifting landscape and local traditions.
