Mallorca water temperature in December: 16°C & city winter
December on Mallorca surprises many Central Europeans: the sea is still 16°C on average. This is not a classic bathing value, but significantly milder than what is known from the North Sea or Baltic Sea in winter. Anyone dreaming of summer, long beach days and warm water should assess December realistically. By contrast, anyone looking for an elegant island trip with sea views, Christmas atmosphere, good gastronomy and premium city hotels will find a very appealing time now.
The Mallorca water temperature in December is at late-autumn level. The sea cools down more slowly than the air, which is why short barefoot moments on the beach or a very brief dip are possible for the hardened. For relaxed swimming without a wetsuit, however, December is usually too fresh.
Swimming in December: yes, but only for the hardy
16°C water feels cool. The first contact is often still pleasantly fresh, but after a few minutes you clearly notice that the body is losing heat. For sporty swimmers, cold-water fans or guests with wetsuits, the sea in December can be interesting. For families, pleasure holidaymakers and everyone who wants to float and relax in the water, it is generally not the right bathing season.
The wind is also important. On sunny, windless days, 16°C air and 16°C water feel milder than the numbers suggest. With Tramuntana, strong northerly wind or changeable weather, the feeling changes quickly. Anyone planning coastal hikes or beach walks should therefore keep an eye not only on the temperature but also on the wind on Mallorca and especially the Tramuntana wind.

The figures show well why December on Mallorca is neither a winter escape in the tropical sense nor pure low season. During the day, 16°C is pleasant for walks, old-town visits, excursions and long lunches on sunny terraces. In the mornings and evenings, however, it becomes fresh with an average of 6.6°C. A high-quality coat, jumpers and good footwear belong in the luggage.
With 53 mm of precipitation and around 6 rainy days, December is changeable, but not permanently wet. For details on classification, it is worth looking at rain on Mallorca and the Mallorca climate table. Anyone looking for a travel time with more bathing suitability should best compare December with the best time to visit Mallorca.
Palma, Christmas and the elegant city season
The greatest appeal of December does not lie in the classic beach holiday, but in the city season. Palma de Mallorca now feels urban, relaxed and festive. The Christmas lights, the Light Festival, boutiques, museums, courtyards and good restaurants make the capital one of the strongest arguments for Mallorca in December.
Premium city hotels in particular are attractive at this time: less pressure than in high summer, often better availability, high-quality spa areas and short distances to culture, shopping and gastronomy. A room with a view over the old town or towards the harbour can offer more holiday feeling in December than a closed beach hotel on a windy bay.
Excursions into the island interior also suit the season very well. Valldemossa is quieter in December, atmospheric and ideal for half a day with cafés, lanes and a mountain backdrop. Sóller combines valley, architecture and proximity to the sea; in good weather, Port de Sóller is also a lovely place for a walk by the water. Anyone who wants to experience the mountain landscape more intensively will find one of the island’s best backdrops in the Serra de Tramuntana.
Comparison with November and January
Compared with the Mallorca water temperature in November, the sea in December is already noticeably cooler, but not yet at its winter low point. In January, the feeling of water and air usually falls further, even though sunny days can still be very pleasant.
