Ibiza does not stop being a Mediterranean destination when August ends. In September, the island enters a different part of the season, with the sea still inviting, beach days continuing and a gradually slower pace across the island.

The shift is also reflected in Ibiza's official tourism messaging, which describes September as a time when the Mediterranean retains its summer warmth while visitors can experience the island's landscapes, villages and coastline at a more relaxed rhythm.

For visitors staying in Ibiza during September, getting out onto the water remains one way to experience the island from a different perspective.

Seeing Ibiza from the sea

Ibiza's coastline stretches for around 210 kilometres and includes dozens of beaches and coves, from broad sandy beaches to smaller sheltered bays.

From the water, familiar parts of the island take on a different appearance. Cliffs, pine-covered coastlines, coves and offshore landscapes become part of the journey rather than simply places reached by road.

Open Boats, which operates from the marina in Sant Antoni de Portmany, offers boat hire and skippered trips departing from Ibiza's west coast. Its current information lists destinations and coastal areas including Cala Salada, Cala Conta and Cala Gracioneta.

September still feels like summer

The official Ibiza tourism website describes September as a month when summer remains present while the island gradually becomes calmer.

The Mediterranean retains the warmth accumulated during the summer months, and beaches and water activities remain part of the island's September appeal.

That makes the month suitable for combining time on the water with other experiences, from visiting villages and heritage sites to enjoying local food and watching the sunset.

From Sant Antoni to Ibiza's west coast

Sant Antoni is particularly well positioned for exploring the western coastline.

Open Boats operates from the town's marina and currently offers several types of boat experience. These include boats that can be operated without a boating licence, vessels for customers with the appropriate qualification and private trips with a professional skipper.

The company lists western destinations such as Cala Bassa, Cala Conta and Cala Tarida, while its wider route references include areas of northern Ibiza and trips towards Formentera.

These should not be understood as guaranteed stops on every trip. The final route can change according to the weather, sea conditions, duration, boat selected and, for skippered trips, the skipper's judgement.

Sunset from the Mediterranean

September also provides plenty of opportunities to combine a boat trip with Ibiza's famous western sunsets.

Open Boats currently offers sunset options on its private skippered trips from Sant Antoni. The experience is centred on spending the final part of the day on the water before returning to port.

The exact experience will naturally depend on the day's conditions and the itinerary selected.

Boat hire options in September

Open Boats' published 2026 season runs from April 1 through September 30.

Its current booking information shows several trip formats, including half-day and full-day options, as well as boats available with or without a skipper depending on the vessel and the customer's qualifications.

For visitors planning a September boat day, checking availability in advance is advisable, particularly for specific boats or sunset departures.

Safety still comes first

Being on the water also means paying attention to conditions.

Open Boats specifically notes that the final itinerary depends on weather and sea conditions. A route that looks ideal on a map may not be appropriate on a particular day.

Before heading out, visitors should check the latest weather and marine forecast, understand the characteristics of the boat they are hiring and follow the instructions provided by the operator or skipper.

The sea should always determine the final plan rather than the other way around.

September beyond the boat

A day at sea can easily be combined with other sides of Ibiza.

The official tourism website highlights September as a good period for enjoying beaches and coastal activities while also exploring the island's culture, heritage, villages, nature and gastronomy.

A morning on the water can be followed by lunch inland, a visit to a historic village or an afternoon exploring one of Ibiza's many coves.

As the days move towards autumn, the island gradually changes pace without losing its Mediterranean character.

Ibiza does not end when August does

August may be associated with Ibiza's busiest period, but September remains firmly within the island's outdoor and coastal season.

The sea continues to play a central role, sunsets remain part of the daily rhythm and boat trips provide another way to see the coastline.

For visitors arriving after the August rush, the combination of Mediterranean scenery, boating and a gradually slower island atmosphere offers a different perspective on Ibiza.

Exploring Ibiza by sea this September

For those staying in Ibiza through the end of September, the coastline remains one of the island's biggest attractions.

From Sant Antoni, visitors can choose between self-drive boats where permitted, licensed vessels or private trips with a professional skipper. Routes can include parts of the west and north coasts, with the final itinerary determined by conditions and the type of trip booked.

September therefore offers a simple way to experience another side of Ibiza: leave the port, follow the coastline, stop where conditions allow and watch the island change from the water.
