Rishon L’Tzion HaGaon HaRav Yitzchak Yosef during his weekly shiur in Beit Knesset Yazdim in Jerusalem, said women are forbidden to bathe on a separate beach where there is a male lifeguard, unless they wear a robe.
It should be noted that most of the beaches in Israel, even those considered separate beaches, have a male lifeguard.
At the beginning of his shiur, the Chief Rabbi emphasized the prohibition on bathing on a mixed beach: “It is absolutely forbidden, not a chumra or midos chassidus, but it is absolutely forbidden.”
As for the women bathing on a separate beach, Rav Yosef ruled: “If the girls go, there must be a female lifeguard.”
“If there is a male lifeguard, who permits him to stand at his post and watch over them? Even on the separate beach, who permits women to bathe in a separate beach when there is a male lifeguard there? Is this permitted? ‘You shall not give an obstacle before the blind.’ Of course, it is forbidden.”
