O Beach is on Carrer des Moli in San Antonio, and it runs in daylight rather than after dark. It opened in 2012 and holds up to about two thousand people around a pool, with a stage, day beds and a restaurant.
The name changed in 2018. It was Ocean Beach Ibiza and became O Beach over a trademark conflict, so older copy and old bookings still carry the longer name.
How the week works
A different themed party each day through the season, with the line-up built round the theme rather than a single resident. It runs roughly from one in the afternoon until eleven at night, seven days a week.
That timing is the real point. It is a full day out that finishes early enough to go on somewhere, which is how most people use it.
The dress code, which is enforced
This catches people out at the door. Swimwear inside is expected, but football shirts are not allowed, and hen and stag fancy dress is refused. You are also expected to leave fully clothed rather than walk back through town in a swimsuit.
It is worth reading the current rules before you travel, because they are applied rather than published and forgotten.
