The Best Time for Dolphin Watching in Mallorca
Mallorca's dolphins are resident year-round, but the boats are not. Month by month: when the fleet sails, what time sunrise falls, and when the sea is warm enough to swim.
The dolphins are here all year. That is the first thing to understand, and it removes most of the anxiety from this question: the bottlenose pods off Mallorca’s north coast are resident, not migratory, and research on the Balearic population has shown they form a distinct group from the dolphins around Ibiza and Formentera.
What changes month to month is everything around them. The boats, the light, the sea state, the time your alarm has to go off, and whether the swim stop is a pleasure or a dare.

The animals are the constant
An acoustic study in Cabrera National Park, off Mallorca’s southern tip, identified at least 82 individual bottlenose dolphins across more than two years of monitoring, part of that population resident in the park year-round. The same species works the north coast, and the operators who sail out of Alcudiamar every morning of the season are following animals with a fixed address rather than a migration route.
Further offshore you may meet striped dolphins, the most common cetacean in the open Mediterranean, which travel in groups of twenty to more than a hundred and come within reach of the coast where the seabed drops to roughly 100 to 200 metres. Several listings also name Risso’s dolphins, which is the operators’ claim rather than a published sighting record, though the deep water north of Formentor is the right habitat for them.
None of that varies by month. What varies is your access to it.
The sailing season, and what limits it
The fleet works the warm half of the year. Weather is the limiting factor rather than the animals: every listing on this site is weather-dependent, the operators cancel up to an hour before departure when the forecast turns, and the standard remedy is a refund or a new date.
Two listings mention the shoulder season explicitly. The Can Picafort sea-cave trip recommends warm clothing at the beginning and end of the season, which is a polite way of saying that a fast boat in April is cold. The swim stops matter here too: the sea off Alcúdia runs about 25°C in July and peaks near 26°C in August, and the swimming season is generally reckoned from June to November. In April and May the water is technically swimmable and practically bracing.
Month by month
April and May. Fewest people, softest light, and a sea that has not warmed up. Sunrise at Port d’Alcúdia falls around 07:09 in mid-April and 06:33 in mid-May, so the dawn boats leave at a civilised hour by summer standards. Pack a proper jacket and treat the swim stop as optional.
June. The best all-round month. Sunrise reaches its earliest around 06:19 in the middle of the month, which means a 5:30am departure, but the sea is flat, the water has warmed, and the August crowds have not arrived. Book ahead anyway — the twelve-seat boats fill.
July and August. Peak everything. Warmest water at 25 to 26°C, longest days, fullest boats, and the highest chance that a small-boat departure is sold out a week ahead. Sunrise moves from 06:32 in mid-July to 07:00 in mid-August, so the alarm gets gradually kinder. Afternoon wind builds earlier in high summer, which is another argument for the dawn departure.
September. The month most regulars pick. The sea is still 25.6°C on average, sunrise has slipped to 07:29 by mid-month, the boats have space again, and the light at dawn is the best of the year. Guest reviews cluster here for a reason.
October. Sunrise at 07:58 mid-month and the clocks go back on the last Sunday, which shifts every departure. The water is still swimmable into November. Weather cancellations become more likely, so build a spare morning into the trip if this is a fixed-date holiday.
November to March. Most of the fleet is not sailing. The dolphins are still out there; the boats to reach them mostly are not.
What time of day beats what month
If you only take one thing from this: the hour matters more than the month. Seven of the ten boats on this site leave before sunrise, and they do it because the sea off Mallorca is flattest before the thermal breeze builds and because the north-coast pods feed early. A mid-morning departure in perfect June weather is a worse bet than a dawn departure in late September.
That is also why the departure time moves all season. Operators set it against the day’s actual sunrise and send the exact time by email the evening before, which is the only time that counts. Our guide to sunrise against daytime departures goes through what the timing changes.
Frequently Asked Questions
What month is best for dolphin watching in Mallorca?
June and September. June gives you flat seas, warm water and fewer people than July; September gives you the same sea temperature, a later sunrise and boats with space on them. August works but it is the busiest and the windiest by mid-morning.
Are dolphins in Mallorca all year round?
Yes. The bottlenose population around Mallorca and Menorca is resident, and a study in Cabrera National Park identified 82 individuals using those waters across more than two years. The seasonal limit is the boats, not the animals — most operators sail through the warm half of the year only.
What time of day is best?
Before sunrise. The sea is at its flattest and the pods are feeding, which is why seven of the ten boats listed here depart at dawn. The sunrise catamaran from Port d’Alcúdia builds a quarter of an hour for the sunrise itself into its schedule.
What time does the sun rise in Alcúdia?
Around 06:19 in mid-June, 06:32 in mid-July, 07:00 in mid-August, 07:29 in mid-September and 07:58 in mid-October, with the clocks going back on the last Sunday of October. Your boat’s departure is set against that, so read the confirmation rather than a time someone quoted you earlier in the season.
Is the sea warm enough to swim on the stops?
From June to November. It runs about 25°C in July, peaks near 26°C in August and still averages 25.6°C in September. In April and May the swim stop is for the brave.
What happens if the weather cancels my trip?
The operator decides, usually the evening before or up to an hour ahead, and the standard remedy is a refund or a new date. You can also cancel yourself up to 24 hours before departure for a full refund on every tour listed here.
Pick your month, then check availability — and if you are travelling in July or August, book further ahead than feels necessary.
