Swim with Wild Dolphins in the Open Ocean São Miguel Azores

Dolphins in the waters around São Miguel

The deep Atlantic around the Azores shelters dolphins all year, with common dolphins and Atlantic spotted dolphins among the species people meet most often, and bottlenose dolphins appearing too. Many visitors search for "swim with dolphins Azores" because here the dolphins live freely in the open ocean rather than in a pool.

The animals are wild and decide how close they come, so each trip is different. On a good day they ride the bow waves and circle swimmers, and on a quieter day the experience is simply being at sea with them nearby.

How the swim works in the open ocean

The instructor guide watches for dolphins, explains the rules and tells the group when it is safe to slip into the water. Staying calm, keeping together and never chasing or touching the animals are part of the briefing, which protects both the dolphins and you. Take time to listen carefully, because the briefing is what makes the encounter calm for everyone in the water.

Because the swim takes place in deep open water, good swimming ability and basic comfort in the sea are needed. With no more than 8 guests, the guide can give personal attention and manage how many people enter the water at the same time. If you are unsure about your level, tell the team when you book and they will advise you honestly.

Best season and sea conditions

The sea off São Miguel is calmest from about June to September, when the surface is smoother and the water at its warmest. Winter trips can still go ahead, but the swell is larger and the water cooler, so some days are cancelled or changed for safety.

If you want to know the best time to swim with dolphins in the Azores, summer gives the best balance of comfort and calm. The afternoon departure follows the morning sea breeze, and the skipper chooses where to look according to the weather and recent sightings.
