What’s the weather like in Ibiza in September?

Located in the Balearic Sea off the eastern shores of Spain, Ibiza has lovely hot weather in September. It’s a hugely popular place at this time because of the late summer sun, warm evenings and nightlife.

Geographical influences

Ibiza’s sheltered by mainland Spain and North Africa, and is relatively flat, so there’s not much difference in weather around the island. The southwest’s Sa Talaiassa mountain does give extra protection to popular spots on the east and west coast though.


The average high temperature in Ibiza during September is 28ºC, so you’ll be spending your days wearing your beach gear. Things stay pleasant in the evenings, with temperatures only dropping to 19ºC at night, so you’ll probably want to choose a room with air conditioning. The average sea temperature’s 25ºC, while humidity’s moderate and ranges from 50% to 90%. Average rainfall starts to climb after the dry summer, but is still only 30mm across eight days with rain.


There’s plenty of sunny weather in September, and you can expect 12 hours of daylight with eight hours of sunshine. UV levels will be high so make sure you’re regularly topping up the sun screen, especially when spending long days in the sun, while sunset’s just before 8.30pm at the start of the month.

Things to Do

If you enjoy hot weather and spending time in the sea then you’ll love hanging out at the beach in September. Head to southwestern Cala Jondal and lovely white sand Cala Xarraca in the north. There’s lots happening in capital Ibiza Town close to the airport, which has an interesting old town area as well as great nightlife. Playa den Bossa also has a great party vibe, and this is where you’ll find famous beach bars such as Bora Bora. Head to Cala Benirrás in the north for a lovely sunset to the beat of bongos.
