How warm does the sea get around Mallorca in the summer months?

The waters surrounding Mallorca typically warm up nicely by mid-June, often reaching temperatures that hover around the low to mid-70s Fahrenheit. This range makes swimming off popular beaches like Es Trenc or Cala Mondrago pleasantly refreshing without ever feeling chilly. By July and August, sea temperatures can creep into the high 70s, inviting long dips and endless snorkelling along the Tramuntana coast or near Formentor’s sheltered bays.

These warm seas make Cala Llombards and the coves near Santanyí particularly popular, as they provide ideal conditions for families seeking calm, clear water and locals enjoying a cooling break from the sun. The Ma-19 coastal road is a great route for island-hoppers to access various beaches with consistently warm water. While the daytime sun is strong, the cool sea breeze keeps things balanced.

A few visitors may notice slight variations near the northern port towns like Alcudia or Pollenca, where water can sometimes feel a little cooler due to currents, but overall it’s a welcoming temperature for swimming, snorkelling, and paddleboarding. If you’re planning to enjoy Mallorca’s world-renowned coastal beauty in early summer or even September, pack your swimsuit—you’re in for soothing, well-tempered seas that enhance the island’s laid-back vibe.
