October weather
Heading for Ibiza in October? This is the month where the last charter flights leave the island. The summer season is ending and Ibiza prepares for winter.

The tourist season ends in October.
The temperatures are in the mid-20s (celsius) and you may still get some suntanning done at beaches that are less crowded than in July and August.
The sea is warm after a long summer, much warmer than in April, May and June. So you can get some swimming done on those nice autumn days.
