Best time to visit
The best time to visit the island to avoid the crowds, but still enjoy the best of the weather, is between the middle of April and first week of June, before all the school holidays! It becomes warm enough to lie on the beach and go for swim in early May, when you can expect long sunny days.
The weather in Ibiza remains warm throughout the year with average nighttime lows dropping to around 11ºC in December and January. The summer months, July and August, can see temperatures reach 40ºC, although the averages are around 30ºC. With sunshine hours reaching double figures, sea temperatures in the mid-20ºC's and barely any rainy days, it's no wonder that Ibiza is the perfect choice for a summer holiday.
With lower temperatures from between 8-15ºC in the winter months, it's a perfect time for outdoor activities and exploring the Ibizan countryside.

Then as autumn rolls around in September, there's more cloud cover, but still enjoyable temperatures of 20ºC.
