How warm is the sea for swimming along Mallorca’s beaches in summer?

During the summer months, sea temperatures around Mallorca typically rise to a comfortable level, making swimming and water sports a real pleasure. Along popular spots like Es Trenc and Cala Mondrago, the water often settles in the low to mid-20s Celsius, which feels pleasantly warm without being stifling. The breath of the sea, combined with gentle winds off the coast, means the water remains refreshing even on the hottest days.

The north coast near Formentor may be slightly cooler due to exposure to open sea currents, but it’s still warm enough for long dips after exploring the Serra de Tramuntana trails. The sheltered coves near Cala Llombards are perfect if you prefer calmer, warmer waters. Visitors travelling via the TIB bus network or by car on the Ma-13 can easily access these beaches, so it’s common to find many sunbathers and swimmers taking advantage of the lovely water from late June through September.

Local fishermen and towns like Porto Cristo often indicate that the water is at its warmest in August, after weeks of sunshine warming the Mediterranean. Even as evenings cool down, the sea retains warmth, allowing for enjoyable sunset swims. Whether you choose to paddle near Palma’s bay or snorkel off the coast of Pollenca, summer water temperatures here balance perfectly with the island’s dry, sunlit climate.
