Mallorca Water Temperature: Month by Month Overview

When is the Mediterranean around Mallorca warm enough for swimming? Holidaymakers ask themselves this question every year. The short answer: from June to October, water temperatures exceed 22°C and invite extended swimming. At the height of summer, the sea off Mallorca reaches up to 27°C — warmer than many a swimming pool. But even during the rest of the year, the water temperature holds its appeal, whether for surfers, divers or the simply intrepid.

Water Temperatures Throughout the Year

Best Months for Swimming in Mallorca

The prime bathing season runs from June to September. During these four months, the water temperature sits consistently above 22°C, and even the most cold-sensitive swimmer will be comfortable. The warmest month is August at 27°C — the sea feels almost like a bath, especially in the shallow coves along the east coast where the water barely reaches your waist for the first fifty metres.

Those who want to enjoy the beaches without the 7 o'clock towel-reservation rush should consider September or October. Water temperatures remain at 22-25°C, the tourist crowds have thinned considerably, and the sun still shines with enough strength to warm the afternoon. Many regular Mallorca visitors consider September the single best month for a beach holiday — all the warmth, a fraction of the crowds.

North Coast vs South Coast: Temperature Differences

The sea around Mallorca is not uniformly warm. The south-east and south coasts (Colonia de Sant Jordi, Es Trenc, Cala Millor) benefit from shallower waters and less wind — here the thermometer in summer often reads 1-2°C higher than on the north coast. The sandy beaches along this stretch warm rapidly in the morning sun, creating pockets of almost tropical warmth.

The north coast around Port de Pollenca and Cap de Formentor is more exposed to the Tramuntana wind. This produces slightly cooler water, but also clearer visibility — a paradise for snorkellers and divers who value being able to see the seabed. The marine life is richer here too, with posidonia meadows that teem with fish.

The west coast at Port de Soller and Banyalbufar lies in the wind shadow of the Serra de Tramuntana and often offers surprisingly warm water temperatures. However, the seabed drops away steeply here, creating a dramatic swimming experience quite different from the gentle east coast shallows.

In the Bay of Palma, influences mix: the sheltered position ensures calm, warm water, though water quality can suffer slightly in high summer due to boat traffic. Beaches like Cala Major and Illetes remain popular nonetheless, thanks to their proximity to the capital and reliably pleasant conditions.

Tips for Planning Around Water Temperature

• Budget tip: Travelling in May or October means lower prices with still-acceptable water temperatures (18-22°C). The shoulder season offers the best value on the island.
• Families with children: From June onwards, the water is warm enough for little ones to splash about contentedly. The gentle, shallow beaches at Alcudia and Playa de Muro are particularly well suited to young families.
• Water sports: Surfers and kite surfers value the winter months (November to March) for the stronger winds — a wetsuit is essential, however. The north coast around Can Picafort and Pollenca sees the best winter swells.
• Diving: The best underwater visibility comes in May and October, when plankton growth is low. Experienced dive operators along the coast offer trips year-round, with the Cabrera marine reserve a particular highlight.
