What to wear to Ibiza Opening Parties: Ibiza sits at 24°C (75°F) by day and 16°C (61°F) at night in May, on island, with a low chance of rain. That means a light base with one warm layer you can carry, broken-in boots or sturdy trainers, and a bag small enough for the gate rules. The crowd leans ibiza, house and elegant, so anything that survives the day reads as right.
