What is the sea temperature like for swimming along the Mallorca coast in summer?

Sea temperatures around Mallorca during the summer often reach a comfortably warm range that makes swimming a real pleasure. Along popular spots like Es Trenc and Cala Mondrago, the water generally warms up to the mid-70s Fahrenheit, sometimes edging into the low 80s during the hottest weeks. This warmth invites both casual swimmers and snorkelers to linger longer in the clear Mediterranean waters. The sheltered coves on the south and east coasts tend to feel warmer due to calm waters and abundant sunshine.

If you venture to Formentor on the north coast or the quieter beaches near Cala Llombards, the water remains inviting though sometimes slightly cooler with gentle breezes coming off the Serra de Tramuntana range. The island’s unique position in the Balearics means that summer water temperatures are consistently pleasant from early June through September. Planning swims around midday ensures you catch the warmest waters, especially on sunny days with little wind. Whether you choose the bustling sands near Palma or a tranquil bay around Pollenca, expect the sea to be welcoming for immersed relaxation or active water sports such as paddleboarding.
