When most people picture Ibiza, they imagine sun-soaked July beach clubs, or the legendary August super-club nights. Yet for seasoned travellers, September is the island’s best-kept secret. With golden afternoons, balmy seas, a more relaxed atmosphere, and an intriguing mix of end-of-season parties and traditional festivals, Ibiza in September offers a very different flavour from its high-summer counterpart. The question is: is it the best time to visit?
Weather: The Golden Shoulder Season
There’s a quiet magic to Ibiza in September. It’s one of those well-kept secrets that seasoned travellers love to whisper about. And a big part of that charm? The weather. Temperatures gently settle around 22 to 24°C, which is warm enough for long, lazy lunches by the sea, or afternoons spent lounging in the sun without a care in the world. Come evening, things cool just enough to feel refreshing - around 16 to 18°C - making it ideal for dinner outdoors or a meandering walk through the cobbled streets of Dalt Vila.
The Mediterranean, too, hasn’t quite let go of summer. The sea lingers at around 22 to 23°C - still tempting enough for a spontaneous dip, a slow paddle along the coast, or a boat ride to Formentera.
Sure, the skies start showing a bit more personality as the month goes on. You might get the odd cloudy stretch or a surprise rain shower. But somehow, it just adds to the atmosphere. The light turns softer, more cinematic; sunsets deepen into rich golds and violets.
Ibiza in September is still warm - but it’s slower, gentler. Less about the party, more about the pause.
Families in September: A Different Kind of Ibiza
For families, the island transforms in September. Waterparks and some high-summer attractions close by early autumn, but plenty remains to entertain children.
-
The Meet the Sea eco-boat excursions from San Antonio run through September, combining snorkelling with marine education, perfect for curious kids.
-
Mercadillos in Ibiza are quite popular and often include puppet shows, games, and activities designed specifically for families.
-
The beaches are calmer, with fewer crowds and safer swimming conditions.
Parents often say this is the month when they can truly relax on the island: warm enough for play, but without the intensity or overwhelm of high season.

Is It the Best Time to Visit?

For partygoers, it’s still electric , world-class DJs, packed dance floors, and the full force of Ibiza’s nightlife before the season begins to wind down.
