Ibiza: Weather in September

Avg. 28°C

September in Ibiza is when the island hits its sweet spot. The weather’s still properly warm, the sea’s perfect for swimming, and the pace starts to ease up after the peak summer madness. You’ll still get those blue-sky beach days and warm, golden evenings – just with more breathing room and fewer queues for everything.
