The Nordau Beach was created in response to the needs of the religious community. In Judaism, religious women and men cannot go to a mixed beach where men and women mingle due to modesty reasons.
However, there is no problem with men and women having all the other enjoyments the beach has to offer with people of the same gender.
Nordau Beach is reserved for religious Jews. The beach is used by women on Sunday, Tuesday and Thursday only and by men on Monday, Wednesday and Friday only.
On Saturday the beach is used by both sexes.
