If you ask islanders when Ibiza's beaches are at their best, a surprising number will say October. The crowds have gone, the sea is still holding the summer's warmth, the light turns golden by late afternoon, and you can finally hear the water. Ibiza beaches in October are a different island from the one on the postcards, and this guide shows you how to enjoy them properly.
Is the sea still warm enough to swim in October?
Yes, for most people. The Mediterranean is slow to cool, and after a long summer the water around Ibiza typically sits in the low-to-mid twenties Celsius at the start of October, slipping down gradually through the month. That is warmer than an English or Irish August, and perfectly comfortable once you are in. Mornings can feel fresher on the sand than in the water, so the trick is to swim in the middle of the day, when the sun is still strong enough to dry you in minutes.
Expect the odd grey or windy day, and the occasional autumn storm that stirs up the sea for a day or two. Check the forecast the evening before, and pick your beach according to the wind: a north wind flattens the south and west coast, while a southerly wind does the opposite. Islanders choose their beach by the wind direction, not by the guidebook.
Sunset creeps earlier every week. Roughly speaking it drops from around 19:20 at the start of the month to before 19:00 by the end, and the clocks go back on 25 October, which brings it forward to around 18:00. Plan your beach day around that, especially if you are heading somewhere with a rough path back to the car.
The west coast: Cala Comte, Cala Tarida and Cala Bassa
The west is the classic autumn choice, because it faces the sunset and the water is a startling turquoise even under a lower sun. Cala Comte is the famous one, with flat rock platforms on either side of its sand where you can lie out and slip straight into the water. It is very popular in summer and much calmer now, and the islets just offshore look best in the last hour of daylight.
A little further south, Cala Tarida is a longer, gentler bay with shallow water and a wide sweep of sand, ideal if you are travelling with children or simply want somewhere easy. Cala Bassa is another west-coast favourite with pines behind the sand and clear, sheltered water. Some of the beach restaurants and chiringuitos along this coast begin to shut from mid-October, so do not count on a specific lunch spot being open; check the day before, or bring a picnic. That is half the pleasure of the season: bread, tomatoes, cheese and something cold, eaten on a rock with nobody else around.
The north coast: Cala Xarraca, Benirràs and Portinatx
When the wind is in the south, the north coast is at its calmest, and the drive there through green hills is worth the trip alone. Cala Xarraca is a small, sheltered bay with a pebbly-sandy shore and excellent visibility for snorkelling, and its water is usually flat and clear. Benirràs is a wide cove with steep cliffs on either side, and the fading light at the end of the day is dramatic there. Portinatx has several small coves next to each other, so if one is windy you can simply walk to the next.
Bring a mask and a snorkel. Autumn is often the clearest time of year for underwater visibility, and the small fish that hide in the rocks and seagrass are much easier to see when there are fewer swimmers in the water. Stay out of the way of any boats, and never touch or pull at the seagrass.
The south: Ses Salines, Es Cavallet and Cala Jondal
The south is Ibiza's warmest and most sheltered corner in autumn, and its long beaches are a good bet when the north wind is blowing. Ses Salines and Es Cavallet sit inside the natural park, with white dunes, juniper trees and a very wide horizon. Es Cavallet is the island's best-known naturist beach, so bear that in mind if you would rather not share the sand with sunbathers who are not wearing anything. The salt flats behind are also where migrating birds gather in autumn, which makes them a lovely early-morning stop.
Cala Jondal and its neighbours nearby are pebbly and deep, with rocky shores that are good for swimming, and the beach clubs along this stretch wind down as the month goes on. If you want a quiet swim followed by a slow lunch, go before the last week of October, when the choice is widest and the mood is calm.
The east: Cala Llonga, Es Figueral and Cala Nova
The east is often overlooked, which makes it ideal in the shoulder season. Cala Llonga is a long, protected bay a few minutes from Santa Eulària, with shallow water and easy parking. Es Figueral and Cala Nova are gentle beaches on the same coast that suit families and older swimmers, with soft sand and clear water. Santa Eulària's promenade and old town are a natural place to finish the day, with its cafés, the river walk and the hilltop church of Puig de Missa all close by.
Practical tips for an autumn beach day
A few small habits make October beach days much better.
- Check the wind, not just the temperature. Choose a sheltered coast for the day and you will have flat, warm water.
- Bring a light layer and a towel large enough to sit on. Once the sun dips the temperature falls quickly.
- Take food and water. Not every chiringuito is open, and some only serve at weekends.
- Watch for jellyfish. They can drift in after a spell of easterly wind. Local lifeguards and the red or yellow flags are the best signal.
- Look after the seagrass. The Posidonia meadows that keep Ibiza's water so clear are protected. If you have a boat, anchor on sand, never in the seagrass.
- Take everything with you. Beaches are quieter in autumn, and cleaning and lifeguard services are reduced, so leave nothing behind.
- Arrive early or late. The best light is before eleven and after five, and parking is easy at both ends of the day.
Why October might be the best time to swim in Ibiza
October will not give you the busy, festive summer atmosphere, but it gives you something more precious: space. It gives you a beach where you can walk for ten minutes without stepping over anyone's towel, a sea that is still warm, and the kind of gold-pink evening that photographers wait all year for. If you have already been here in high summer, come back once in autumn and see the same coves as the locals do.
