Ribersborgsbadet is an official nude beach since 1998. The Nude Beach has been moved a bit futher out. It is signposted.
It is easy to find Ribersborg in the south of Malmö. Take bus line 32 to bus stop "Nordmannagatan".

When you arrive at Ribersborg, go to Pier 10 past the beach for the disabled. You need to be able to swim since you bath off the pier in deep water.
There is a nice sheltered lawn for sunning and BBQ is allowed. However, you have to bring your own grill and there are no tables with benches. Be careful with the lawn.
