How warm is the sea around Mallorca from spring through late autumn?

From late spring through to the end of autumn, the waters around Mallorca offer inviting temperatures for swimmers and water sports enthusiasts alike. As the island moves into May, the sea typically warms to around 16 to 18 degrees Celsius, which many find refreshing but sometimes a little brisk on windier days, especially at exposed spots like Cala Formentor or the northern cliffs of the Serra de Tramuntana. By June and July, especially around popular beaches such as Es Trenc or Cala Llombards, the temperature usually climbs into the comfortable low twenties, making it ideal for swimming and snorkeling.

August is the peak, with sea temperatures often reaching between 25 and 28 degrees Celsius. This warmth extends well into September and early October, perfect timing if you’re visiting for the Festa de l’Ametler in Inca or the laid-back cafés in Valldemossa. Even as November approaches, the Mediterranean remains relatively mild, particularly on the southern coast near Campos or the bays around Pollenca, with water temperatures rarely dropping below 18 degrees Celsius. This balance gives a long, flexible season for beach lovers and water adventurers to enjoy Mallorca’s exquisite coves and clear waters beyond the peak summer crowds.
