The beach is beautiful and long so almost impossible to imagine feeling really crowded. We were there at Eid at the end of Ramadan and so it was very busy but still lots of space. A kilometer from the Medina and Port are well equiped surf shacks where the emphasis is on kite surfing - which tells you that this is usually a very windy place. Great for the kites but not so good for sunbathing. Temperatures are also much lower than Marrakech - which in August was a good thing.
