Ibiza Weather in September
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.
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.
